Aly,

I just saw this thread now. As far as peeing and pooping, have you been stimulating her to pee and poop after feeding her? Kittens that small rely on their mamas to stimulate them into doing that.

Take a soft washcloth and rub her in her "private" area. You'll know when she goes because it'll feel warm and wet.

You need to do this after every feeding. Hope this helps.

Another thing you might try to do is leave a radio and nightlight on.
