Moving kittens ??????

I have a cat named bluegirl, she has 2 kittens named Bingo and oreio. The mama cat keeps moving the 2 kittens around the house, is she trying to tell us something or is this just normal for mama cat's too do with her frist 2 kittens ? 

She is probably seeking privacy and quiet. How old are the kittens?

It would be better for mom and babies if you could put her nest in a closet in your bedroom and move her food, water, and litter into this bedroom for her. Leave the closet door ajar, but close the bedroom door, and limit noise, light, and activity in that room until the kittens are older.

Cats need to feel that their kittens are in a safe place.
