Is Cloud eating, drinking, having normal poop and pee output? Is she hopping about normally?
I just looked back at the pics, and she doesn't look really fat to me. If she is bloated, give her pediatric drops for babies that have colic- I believe a lot of people here use "Gas-X"... I haven't had any gas problems, so have no anecdotal experience to share, but I am thinking I better buy something to have on hand in case I need it.
Some does don't get their milk in until the second day, so don't worry too much about them not looking fed yet. I would clean their butts up with warm water and then dry them off so you can see if they continue to have problems.
I hope your gut is wrong, and you are just suffering from "Nestbox neurosis" and all will be fine! Let us know how she is doing later.
Cloud had her kits. She still looks pregnant. I don't think she fed them. They are sporting dirty butts. I don't hold out much hope. I picked her up & checked her over I can't tell if she is okay or not. She just looks bloated a bit. Could be a winter coat deal I guess but my gut is screaming something is wrong. Going to give it till tonight & then I will worry.
