I have maternal tubs so each female gets their babies all to themselves, but occasionally I'll get some overflow from too many producing at the same time. When that happens, I'll use a communal tub for the moms too. Don't be concerned with babies all over the place or "baby snatching". I'll have 3-4 moms snatch babies back and forth all day but they'll still get the job done. I'm sure you'll do fine, although I have noticed first time moms tend to be less skilled at taking care of babies as seasoned vets
