My little girl is 16 weeks old and she loves to have a comforter to rub against her face, normally we use muslins but she does have one bear comforter she uses also... my question is what do you guys do if it becomes something they cant sleep without?

I want to maintain safe sleeping and so far we are managing that as at night she can sleep without anything but in day she likes them for naps which is fine because shes never alone for her naps as just naps wherever we are....

But what if it starts becoming a night time thing- in day if I take it away it usually wakes her....
