Well...we had our 4 month checkup today, and my fears were confirmed. My little peanut gained a mere 1 pound and 4 ounces in a little over 2 months!! I just don't understand, her wet and poopie output is great, she's content after nursing, so why isn't she gaining??? I only nurse off one side per feeding, so the Dr. suggested I try both sides each feeding and she wanted to see me again for a weight check in 2-3 weeks...I don't know what else to do!! I've nursed both sides before, and that didn't seem to make any difference! I guess I'll just try and see...but some other suggestions would be great....what is wrong with my milk that it doesn't have enough calories for her...or is it her? Why doesn't she eat more if she's not getting enough calories?? Help me understand this please!!
