Please use your child's weight and height to find the most appropriate and safe size for them. A sleeping bag should be fitted around the neck and the armholes to avoid your baby slipping through. It should also be bell shaped in the bottom to allow for easy leg movement. Please do not size up to the next size until your child meets the weight requirement, for safety reasons.

This is our 12th ergo pouch sleeping bag - with four kids (!). It’s the only brand I trust and would recommend. They are just so good. I preferred the sheeting 3.5 tog without the arms, but since they are discontinued we get the sleeved version now. It’s a bit harder for kids to get on and off by themselves and you had more flexibility in terms of warmth without the sleeves, but it would be no reason for me to change brands. The materials are just so superior! You unwrap your products and of course it needs the customary wash, but there is no smell or funny feel to it at all. It’s beautiful from the first second!

Love this sleeping bag. It's got plenty of room for my 8 month old son to grow into. It's definitely keeping him warm during this cold Melbourne winter and I love that his arms are kept warm as well. My partner and I definitely prefer it over the sleeveless styles for winter

So great. My son is a tall 16 month old so sized up to the size 2-4. He’s so comfy and snug. Is also sleeping until 7 now because he’s so snug!
