If sleep, Why a child doen't like wear blanket?

Welcome to the Lot, bOnkzs! I suspect it's just a matter of habit. I'm not comfortable without a blanket, but a lot of people, especially in hot climates like the one here, never use them.

Because we just don't like the feeling of being covered by a cloth. Maybe we don't like texture. Happy MyLotting!

my children also didnt use to like their blankets and it used to annoy me, as soon as i covered them back up they would kick it back off, even in their sleep. but now they have even worse habit, they now put the duvet right over their heads, i hate that, i panic that they wont be able to breathe properly.
