Hi, I have a 1 year old who needs to get the next size up in sleeping bags or move to a quilt. What do you recommend for the ages 1-2 years and still in a cot? Thanks!

Red Nose recommends that you avoid using any soft, padded or loose bedding while a child is in a cot.
It is preferable to continue using a sleeping bag until your child moves to a bed.

Soft bedding is dangerous in a cot and should not be used. Soft bedding includes pillows, quilts, doonas, soft toys and bumpers. Soft bedding may cover the baby’s face and obstruct breathing and/or cause overheating.

Older babies in a cot can be at an increased risk of a sleeping accident by using pillows and bumpers as a step to climb up and fall out of the cot. It is safer to wait until the child starts to sleep in a bed before introducing a pillow or other soft bedding.

There are no doonas, quilts, loose bedding or fabric, pillows, lambswool, bumpers or soft toys in the cot
