question abouy feedings

Mkay&Billy2011

My baby is ten weeks old and weighs about ten lbs five oz as of her two month appt. How much is your baby eating at a feeding and how often? I have been breastfeeding and then she was getting frozen breastmilk while I was gone but I'm sure my supply is decreasing and I am out of frozen milk so she breastfeeds some and then I give her some formula because she doesn't get satisfied from me. I'm worried about feeding her too much or not enough. So I'm looking for some input. Thanks
