Hi and welcome to YT!
you will find a lot of information here and many helpful people. We have a breeders section where you should post any questions you have about your little girl and your more likely to get a breeder response with good information there.
I have fostered mothers and litters and the mother does require more food while pregnant and while nursing. Ask the breeding section about what kind of food and how much she should be getting right now.
good luck
