No, but if they are new mothers and it is their first litter, they might sit on the babies for a day. Afterwards and from time to time, she will look for food to eat, and water, because she has to produce enough milk to feed her babies. If she sits on her babies constantly or a lot, it's probably because there is little or no insulating materials in the cage. You must supply insulating material, or the babies will die of hypothermia. You can supply insulating material, such as shredded newspaper or shredded paper from your paper shredder; wood shavings, or even the kind of straw that horses and cows eat. Don't disurb the mother mouse and her babies for at least a week or two.

Type your answer here... Yes... but only if you sit still long enough.
When they can sit up on their own.
they sit on their eggs about the same amount other birds do and they do not bury their heads in the ground.
Babies should use a rear-facing child safety seat in the car.
Most babies sit by self in 6-8 th month. However it all depends on his moments from Day-1. As parents/guardians make the baby sit against couch with support, Regularly massage babies to give strength and comfort them with pats and hugs. Push toys away from them so that they stretch to grab, etc..
There's a range, but most are able to sit up (if you put them there) at 4 to 6 months.
