When is someone too old to sleep with a baby blanket?

Loaded question. Why do you ask? If an 80+ year old wanted to take his/her baby blanket with them to bed i wouldn't care or stop them. Kids usually give up these comfort things when they begin to sense peer pressure at school age.I do not recommend taking them from the child, ever! a kid should be provided his/her own space to decide what comforts them.Adults can be creative in finding ways for kid to give it up.
