How to make a cute, cosy and safe baby bed
Here’s what you really need to know about safe sleep It’s easy to get caught up in the dreamy images of babies curled up in plush bedding, surrounded by teddies and soft textures. But when it comes to real-life safe sleep, less is definitely more. Whether you’re still setting up the nursery or your baby is already here, creating a secure and snuggly sleep space is one of the best things you can do for their wellbeing - and your peace of mind. Understanding SUDI SUDI stands for Sudden Unexpected Death in Infancy, and while it sounds confronting, knowing the facts can be empowering. SUDI includes deaths from a range of sleep-related causes, including accidental suffocation and unexplained deaths (previously called SIDS). In New Zealand, it’s one of the most common causes of death for babies under one—but the good news is, there’s a lot we can do to reduce the risk. Research shows that a baby’s sleep environment plays a big role. Things like sleeping baby on their back, using a firm mattress, avoiding overheating, and keeping their sleep space free from loose items all help create a safe place for them to rest. SUDI is most likely to occur between 2 and 4 months, so starting safe sleep habits from day one is key. By following a few simple guidelines and making thoughtful choices around where and how your baby sleeps, you're helping create the safest possible start. Safe sleep isn’t about fear—it’s about giving your baby the best chance to thrive. Safe sleep basics: what to know One of the most important ways to reduce the risk of SUDI is to make sure your baby sleeps on their back, in their own bed, and in the same room as you for at least the first six months. Their sleep space should be simple, uncluttered, and specifically designed for babies. Keep your home smokefree, avoiding overheating, and ensuring your baby’s face remains uncovered during sleep. Here’s what that looks like in practice: Choose a compliant cot A safe night’s sleep starts with a compliant cot. In New Zealand, all cots must meet the AS/NZS 2172 safety standard, which covers features like the minimum depth, spacing between slats, and secure construction. Look for the safety label when buying, and avoid using broken or modified cots - even hand-me-downs. Having baby in their own cot or bassinet reduces the risk of accidental suffocation and overheating. Shop our safe and gorgeous range of bassinets and cots here. Pick a firm, snug-fitting mattress A firm mattress that fits tightly within the cot frame is essential to prevent your baby’s face from pressing into soft surfaces or becoming wedged in gaps. The mattress should be flat and supportive - not shaped or elevated, and free of damage. Bonus points for breathable materials and easy-clean features, especially if you’re dealing with frequent night-time messes. We stock several options that will keep your baby safe. Shop here. Stick to the essentials To keep your baby cosy and safe, layer their sleep space with: Waterproof mattress protector – Ideal for leaks and spills, a protector helps keep the mattress clean and hygienic. Choose breathable options like merino for added comfort. Fitted sheet – This is where you can add your splash of style. Soft, well-fitted cotton or merino sheets keep things simple and sweet without compromising safety. Swaddle or sleeping bag – Skip the loose blankets. Swaddling (if age-appropriate) or using a well-fitting sleeping bag helps regulate baby’s temperature without the risk of fabric covering their face. What not to include Soft toys, bumpers, loose blankets, pillows, or positioners should never be in the cot. These items, while cute, can increase the risk of suffocation. Even mobiles and cords should be securely out of reach. The safest bed is a clear one - nothing but baby, dressed for the room’s temperature, on their back. Monitor with peace of mind If it helps you rest easier, consider a reliable video or breathing monitor. While not essential, these can offer extra reassurance during naps and overnight, especially during the early months. Shop our range of monitors here A minimalist bed is a safe bed We know it might feel counterintuitive when you’re eager to make your baby’s space feel warm and welcoming. But safety should always come before styling. Keep it simple until your little one is at least 12 months old, when they’re better able to move around and regulate their temperature.

Reduce the Risk of SIDS
How to help keep your baby safe Entering the world of parenthood comes with its fair share of anxiety, from wondering how different your new life will be, to the worry of being responsible for a new little person. Sudden infant death syndrome (SIDS), previously known as ‘cot death’, is the unexplained death (typically during sleep) of a seemingly healthy baby. While SIDS is a very real threat, with a little knowledge you can reduce many known contributing factors. Back to sleep You’ll no doubt hear this on repeat from midwives and Plunket nurses as soon as your little babe comes along and for very good reason. Babies who sleep on their stomachs are much more at risk of SIDS. While it’s not 100% understood exactly why experts believe it could be about re-inhaling stale air. Once your baby can happily roll over by themself, you don’t need to worry about sleeping positions any more. Make it a strictly smoke-free zone Smoking (and exposure to second-hand smoke) during pregnancy not only puts your baby at risk of health issues but increases the risk of SIDS too. It’s thought that nicotine can wreak havoc on a mechanism in their brain which senses a lack of oxygen and triggers breathing to start (called auto-resuscitation). So make sure it’s strictly a smoke-free zone when you’re pregnant and when your little one arrives, and that your family and friends are on board too. Welcome your new (temporary) roommate It’s widely recommended that your new babe bunks in with you (in their own safe sleeping space) for at least the first four to six months. This isn’t always practical for light sleepers, in which case a good breathing movement monitor set up in their nursery will give you peace of mind. A safe spot for slumber While room-sharing is recommended, bed-sharing isn’t. It can be so tempting to savour that extra time snuggled up in bed with your new babe, but bulky duvets, pillows and even an adult rolling can spell danger for little ones. Setting your baby up with their own safe space (like a portable Moses basket ) within arm’s reach is your best option. Be prepared to be suddenly jolted awake and find yourself sitting up in bed or a nursing chair with your baby in your arms – sleep deprivation can really grab hold of you in the early days. Sleeping with a baby on a chair or sofa is very dangerous, so to avoid this as much as possible, use the middle-of-the-night feeds as opportunities to clear out and edit that day’s photos on your phone (no doubt there will be plenty!) Your phone’s blue light will help keep you alert. Baby, it’s cold outside It’s important to make sure the room where your baby is sleeping is at a comfortable temperature. Bundling up babies at all times is an outdated theory – overheating is another substantial SIDS risk. Higher temperatures can put babies into a deeper slumber, making it difficult for them to wake if their breathing is obstructed. The recommended room temperature for a baby is 16 to 20 degrees, with around 18 degrees being ideal. To check your baby’s temperature, feel his back or tummy – it should feel warm. A great way to check the temperature of their nursery is with a combined nightlight/temperature sensor like the Moon Nightlight . Blankets (and everything else) be gone All those cute blankets, animal-shaped pillows and snuggly little toys that create a cosy-looking cot will need to stay in storage until your baby’s first birthday. Until then, all you need is a fitted sheet and wearable bedding like a Merino Sleep Pod to keep them warm. The key is to avoid anything that may cover their face and restrict breathing. Breastfeed if possible Experts aren’t sure why, but breastfeeding can significantly lower the risk of SIDS. The theory is that breastfeeding promotes the sucking and swallowing action, which develops muscles that keep the airway open while boosting brain development. Breastfed babies are generally lighter sleepers, too. This might not sound like a benefit at 2 am, but anything that helps reduce SIDS is a big plus. A big tick for pacifiers There tends to be negativity around using pacifiers, but they can not only be life-saving for unsettled babies during car trips, but also literally life-saving. Once again, it’s a bit of an unknown how pacifiers help, but there is a clear link – babies who use pacifiers are at lower risk of SIDS. As with breastfeeding, this could be due to more developed sucking and swallowing muscles that help keep airways open. If you’re breastfeeding, wait until this is well established (at least 4-6 weeks) before introducing a good quality silicone pacifier . Do what you can to reduce the risk While there are still a lot of unknowns with SIDS, being armed with what you can do to reduce as many risks as possible should put your mind at ease. Keep in mind that the risk of SIDS decreases after six months and is pretty rare after a baby’s first birthday.

When Pets Meet Babies
Welcoming Your Baby and Fur Baby Together 🐾👶 For many families, pets are our first “babies” – loyal companions who’ve shared the couch, the bed, and plenty of milestones. So when a new human baby comes along, it’s natural to worry about how everyone will adjust. The good news? With a bit of preparation and kindness, your pet and baby can build a beautiful bond from the very beginning. Start with Your Pet’s Personality 🐶🐱 Every animal is different, and how you prepare depends on your pet’s species, temperament, and past experiences. While goldfish or guinea pigs usually require little adjustment, cats and dogs can be more sensitive to the changes a baby brings – new sounds, smells, routines, and less attention. If your pet hasn’t spent much time around children, consider slowly exposing them to baby-related sounds (like crying or giggling) using recordings beforehand. This can help desensitise them and reduce anxiety once baby is home. A Gentle Introduction is Key Before baby arrives, introduce your pet to baby items like the pram, cot, or bassinet. Let them explore at their own pace so these new additions don’t feel overwhelming later. You can even go for practice walks with the pram to help your dog get used to the change. When baby comes home, offer your pet something with baby’s scent – like a swaddle or hat – before the first face-to-face meeting. For dogs, initial introductions should be calm and ideally on leash, in a neutral space like the front yard. For cats, allow them to approach in their own time and retreat when they’ve had enough. Reward your pet for calm, gentle behaviour with treats or praise to create positive associations with baby. Safety First – Always 💛 No matter how friendly or socialised your pet is, never leave them alone with your baby. Even well-meaning pets can act unpredictably when startled or stressed. Cats may try to jump into the bassinet to cuddle up, which can be dangerous. Consider using a cat net over the cot or keeping the nursery door closed. For dogs, teach them to respect baby’s space and avoid licking or nudging the baby. Once your baby becomes mobile, always supervise interactions and start gently teaching respectful handling – this not only keeps everyone safe but helps your child grow up with empathy and confidence around animals. Create Safe Spaces for Everyone As your household routine shifts, pets will appreciate having a quiet, baby-free zone to retreat to. Use pet gates or closed doors to keep their food, bedding, and litter trays separate. This not only protects your pet’s resources but keeps curious toddlers away from things they shouldn’t be touching (or tasting!). Make sure escape routes like cat doors are secure, and create high perches or quiet corners where your cat can safely observe without feeling overwhelmed. Managing Allergies and Cleanliness Pet hair is a common allergen, and while it’s impossible to know if your baby is sensitive right away, there are a few preventative steps you can take: Vacuum regularly (a pet-specific vacuum can help). Bathe or groom your pet as advised by your vet. Keep pets off nursery furniture and out of the baby’s sleeping space. Consider using an air purifier in high-traffic areas. It’s also a good idea to wash baby’s hands after contact with your pet – especially once they start crawling! Don’t Forget About Your Pet’s Routine ❤️ Newborns take up a lot of time and energy – and pets can sometimes feel left out. Sticking to familiar routines, like walks, feeding times, and play, helps them feel secure. Enlist friends or family to help out with dog walking or play sessions, especially in those early weeks. Cats benefit from mental stimulation too – puzzle feeders or interactive toys can be great for independent play. Some parents also find that having their pet involved in small baby routines (like sitting nearby during nappy changes or walks in the pram) can help strengthen the bond early on. Growing Together: A Bond Like No Other With time, patience, and gentle consistency, your baby and fur baby will adapt to each other – and may even become inseparable friends. Watching them grow up side by side is one of life’s simple joys 🥰 If you’re getting ready to welcome a baby into your home and have questions about creating a calm, safe space for both little ones and furry friends, don’t hesitate to get in touch with the team or pop into your local Dimples store – we’re always happy to help.
