Too much ME time for mom?

Hi everyone -- I'm new here, but sooo glad to have found you all. I have been reading posts non-stop since my Emma had a litter of 3 Thursday morning. My question is: starting today, she has been spending a LOT of time away from the babies. She hasn't moved from the nest since she had them, only to use the litterbox. But today, she's been all over the house, visiting, looking out her favorite window, watching the bird (we have a bird), etc. Babies are quiet, sleeping. How much ME time should I expect her to want? Thanks for your input/reassurance - you all have been VERY supportive these last few days (even if you don't know it!)

as long as the babies are well fed and clean i wouldnt worry. in the wild she wold be sing this time away to hunt.

just keep and eye on them and that shes feeding them.

I agree, if the kittens are satisfied and sleeping all in a bunch then Mom-cat can go visiting and bird watching...lol
