Yes. Every night our daughter ( age 2 ) sleeps with her two husky stuffed animals one is supposed to be the mom the other is supposed to be the baby, she also has attached herself to her birp cloths and sleeps with them at night. Most of the time she throws everything out of her crib though. Our son ( age 1 ) also sleeps with a birp cloth.
My son is 4 and has a blankie. He takes it every where we go. But he will leave it in the car, and in his backpack at school. He just has to know that it's near by. But he cannot sleep without it.
my son can NOT sleep without his nite nite(blanket)...he LOVES that thing even tho it has a hole in it and is all stained(I've washed it a million times)
