Cats and kittens

Woke up from a nap today and found that my cat had moved all her kittens over to my bed where i had been sleeping, and i mean like RIGHT next to me. I found it cute and all but was worried as to why she did it, Ive made a makeshift nest for them up there but plan on moving them back to their actual nest tonight, didnt want to move them too early so momma cat could calm down.
