Why use a sleep suit?

  • If your child is starting to move around more, walk or climb, the legs on a sleep suit are perfect for allowing movement.
  • If your baby or toddler is starting to get frustrated in their sleeping back a sleep suit is a great alternative, whilst still keeping them toasty warm.
  • Comfort baby and keep her warm, without the need for additional bedding.

  • Baby will be the right temperature all night - there are no sheets or blankets to kick off while in a sleep suit, so your baby won't wake up cold.

  • Ensure baby sleeps safely - there are no sheets or blankets to wriggle under or pose a suffocation threat so you can help create a safer sleep environment for baby.

  • A sleep suit is a positive sleep association meaning that every time they are put in their bag, it's a strong cue that it's time to sleep.

  • Complete the bedtime routine in baby's sleep suit - you can cuddle your baby and then place them in their cot, which makes settling much easier.

  • A sleeping bag is a sleep environment that is safe and familiar, so when taking your baby sleeping bag on holiday or when visiting family and friends, your baby sleeps has their usual sleep cue.
  • Travel sleeping bags, which have a slot of the pushchair buckle, helps baby with a regular sleeping routine, even when you are are out as it also allows your child to go into a pushchair or a buggy and then simply transfer your baby to their cot or bed.

What is the difference between a sleep suit and a sleeping bag?

Sleep suits are like sleeping bags with legs! They are as warm as their sleeping bag equivalents, but the legs are great for active sleepers and toddlers who are starting to walk and climb.  

Is a sleep suit or a sleeping bag better for my toddler?

It really depends on your child. If a sleeping bag is working well for your younger baby there's no reason to swap to a sleep suit, however if your baby is becoming more active or frustrated by their sleeping bag, it may be time to swap to a sleep suit instead. Sleep suits are great for toddlers who are moving to a big bed and will be getting out and walking around and they also work well for little ones who've never been in a sleeping bag, but are starting to kick their blankets off!

Which is the best sleep suit for my baby?

The best sleep suit for your child will depend on a number of factors including your budget, baby's age, how warm their room is and what sort of fabric you're looking for. We have one of the largest ranges of sleep suits in New Zealand, so there'll be something to suit every baby or toddler.

How many sleep suits do I need for my baby?

We recommend you invest in 2 sleep suits for your baby or toddler. This is particularly important in winter, when washing takes longer to dry and also you really need your sleep suit to keep your baby warm.

Can you sleep in them without a blanket?

Yes, sleep suits are designed to use on their own, without additional blankets. Simply layer up clothing underneath depending on how cold the room is and add a pair of merino socks in winter.

What size should I buy?

The sizes are based on average sized babies, so do consider if your baby is extra big or small for her age. We recommend that you buy the right size for your baby now, rather than worrying about it lasting for next season. The Woolbabe sleeping suits are generously sized, so If you choose to upsize the crotch area may be too big, which can cause your child to fall when walking around.

If you're not sure about the size, carefully open your purchased sleep suit, keep the packaging and try it on. We are happy to exchange the size provided the suit is returned to us in original, saleable condition, with all packaging intact.


What is a TOG rating?

The tog rating indicates how warm the sleep suit is and relates to how many blankets the bag is equivalent to. The higher the tog, the warmer the bag. For example, a 2.0 tog bag is equivalent to just over 2 blankets.

Merino bags are not tog rated because they have naturally temperature regulating properties.

(Please note the tog link is for sleeping bags, however the same advice applies for the equivalent sleep suit

What do I dress my toddler in under these?

It really depends on the temperature of your little one's room and the type of sleep suit you have. A Woolbabe Duvet Sleep Suit or a 2.5 tog or 3.5 tog cotton sleep suit is perfect for winter and temperatures of approximately 14-22 degrees. The duvet weight sleeping suits are lined with cotton and filled with 100% merino wadding, so are lovely and thick.


A 3-seasons Woolbabe Sleeping Suit or a 1.0 Tog cotton sleep suit would suit room temperatures of approximately 18-28 degrees. The 3-seasons is made from 2 layers of merino/organic cotton blend fabric.

How do you keep their feet warm?

Over winter, pop on a pair of merino socks - we love Lamington's!

Are they ok for babies with eczema?

Woolbabe sleeping suits are lined with 100% cotton, which is great for sensitive skin. The outside layer is 30% merino and 70% organic cotton blend.

How do I wash my sleep suit?
