Hmm, I don't know how you can overfeed when you are nursing, they usually don't take more than they need. The best advice is to offer a lot skin to skin contact and see if your baby starts to root. It is also a good idea to take a bath together, and see if she would want a boob. You can also nurse while she is napping/sleeping as if you were doing a dreamfeed. Especially night nursing is good at increasing your supply.
