Hi, at what age is it ok to introduce a comforter for little ones to sleep with? My little one sucks on the sleeve of her sleeping bag and I’m trying to get her to stop. She is almost 1 Thanks

A soft toy can be placed in baby’s cot after 7 months.
Soft toys should never be placed in the sleeping environment of an infant under seven months of age. Soft objects in the cot can be a suffocation risk

Keep soft toys out of the sleeping environment for babies under seven months of age because they may cover the nose and mouth and interfere with breathing.
Some babies over seven months of age may appreciate a small object such as a soft toy to provide comfort and connection (transitional object) during times of separation from their parent.
