The mother can eat the babies if there's no water or food when they want, you are lucky to have them all alive, so, I advise you getting a water bottle, as the bowl is dangerous, there are some who fit in bins and gallons, I use bin cages and I have them, if you can't find one, then buy a bottle with a little hole, then put a wire, I'm portuguese, I don't know how to explain.
If the first litter was weak and the mother couldn't take care of them correctly then you shouldn't have bred her again.
But Vanilla if I can remember well, was inbreeding?? Or am I wrong? When was the first litter?
The water bottles I'm talking about are these:

Or something similar to them, with that little hole to put the wire, the wire WILL NOT have contact with the Hamster.
A holder like this would be helpful as well:

Sorry, I don't have the time to read every post after my last one, but meh, I'm trying to be active on Chicken Smoothie again, but I've been so, so busy.
