When babies turn a year old, their motor skills are sharp enough to roll over and push objects away from their face, affecting their breathing. In this case, it’s the blanket they won’t be able to remove below one year old. This age is very sensitive as your baby still hasn’t developed motor skills. So, extra care and precautions need to be taken when putting them to sleep. There should be no pillows, stuffed toys, or anything soft in the crib, for they could also suffocate in them.
