I've only had the kittens for 3 days, and I can already see the growth. Their paws have gotten so big! Mama has been really good with allowing us to handle the kittens. Every once in a while I fill up a water bottle with hot water, cover it in a towel, and toss it in the back of the crate, in case the babies are getting too cold.
I had another scare this afternoon. One of the babies looked smaller than the rest, so I took away two of the "fat" kittens, which gave him a little more space to nurse. Apparently, that's nothing to worry about either, it's common to have a runt in the litter.
