Who's the Mother??

Check the nipples. The mother should have more prominent nipples, and the fur around them will be messy or even pulled out from being suckled on.

Thanks, that was the instinct I went on earlier and separated them from the rest of the group, but I started doubting that I got the right mother because I've not yet seen her nursing them. Her nipples aren't as prominent as I would think they would be but they are the most prominent of the bunch.
