moms moving kittens

ok im a new mom here. both of my females had their kittens a week apart. they have to keep the kittens in the same box. they nurse each others kittens and keep them clean. here is my dilema. the female that had her babies first (cookie) keeps wanting to move all the kittens. they have been in that box since the first birth 4 weeks ago. now all of a sudden she wants to move them. im afraid she will move them in a place that i cant find them again. how do i keep her from doing this?

I don't think you can unless you keep the door closed. Maybe if you separated the kittens she would not want to move them? Can you offer her a new place in the same room and keep them apart that way? Just an idea.
