Shop Baby Sleep Sack by Age: Newborn to Toddler
Find the safest fit for every milestone in your child's life. At Baby DeeDee, we have designed a complete system of wearable sleepwear that grows with your baby, from their first night home to their first steps. Our selection guarantees a restful night's sleep for the whole family, offering specific solutions for every stage (from the cocoon-like security of a newborn to toddler sleep sack to the freedom-focused designs for active walkers).
Newborn to Infant (0-18 Months)
For the earliest months, your baby needs a sleep environment that mimics the womb while ensuring safety. Our infant collection serves as the perfect transition from the swaddle, providing a wearable blanket that gives your baby continuous warmth without the suffocation risks of loose bedding. These sacks are essential once your baby shows signs of rolling over, featuring our distinctive shoulder-snap design that makes midnight diaper changes easy and quick without disturbing their sleep.
Toddler Sleep Sacks & Walkers (18-36 Months)
As your child begins to stand, crawl, and walk, their sleep needs change. Our toddler collection appeals to these little explorers with designs that accommodate movement. This includes our "Sleep Kicker" (or sleep sack with feet), which features ankle cuffs that let your child safely and freely move around their crib or bedroom. It provides the same level of warmth as a conventional baby sleeping bag but removes the trip hazard, allowing energetic toddlers to have the freedom they desire.
Understanding Sleep Sack Sizes & Fit
Whether you have a petite newborn or a tall toddler, getting the right fit is critical for safety. We provide detailed sleep sack sizes based on weight and height, ensuring the neck hole is snug enough to prevent slipping, while the bell-shaped bottom promotes healthy hip development. From our size Small (0-6m) up to our toddler sizes (3T), we ensure your child remains in the ideal body position for safe, comfortable sleep throughout the year.
Frequently Asked Questions
When should I switch from a sleep sack to a sleeping jumper?
Once your baby starts to pull up to a standing position or walks. Since a baby onesie sleep sack is just right for an infant, it is important to note that a jumper has holes on its legs that enable toddlers to move about in cribs without tripping.
What should my baby wear underneath a onesie sleep sack?
What you put underneath will depend upon the room temperature you are in, as well as the TOG of your sack. For a typical 2.5 TOG baby sleep sack, you will usually put a long-sleeve bodysuit or footed PJs underneath. This sack is meant to be your baby’s sole blanket, so it is best to keep it simple underneath.
Are baby sleeping jumpers safe for walking?
Yes. Our baby sleeping jumper, made especially for toddlers who are beginning to stand, crawl, and walk, will appeal to your little explorer. This creative design, often referred to as a "sleep walker," has ankle cuffs that let your child safely and freely move around their crib or bedroom. It provides the same level of warmth as a conventional baby sleeping bag but removes the trip hazard.
Why use a wearable blanket instead of a regular blanket?
The loose blankets inside the crib might be dangerous in cases of probable suffocation or entrapment. A baby onesie sleep sack eliminates these hazards by ensuring the "blanket" stays securely on your baby, keeping their face clear. The baby cannot kick the covers off either, so this keeps them warm and sleeping soundly through the night.
How do I choose the right size?
Sizing is based on weight and height, but most importantly, not just based on age. A proper fit is very important for safety: the neck hole needs to be snug enough that your baby's head cannot slip down inside. Whether choosing a newborn to toddler sleep sack or a jumper, always refer to our size chart to ensure a secure and comfortable fit.
