Underweight 4 month old doesn't want to eat!
So, my 4 month old just had her wellness exam this past Thursday, and her doctor said she is underweight! She is 24 3/4 inches & 12lbs 3oz. The doctor said she is only in the 3rd percentile for weight & wants her to gain. She scheduled us for a weight recheck in 1 month and told me to start supplementing with formula & giving vitamin drops. She has been exclusively breastfed, and while I do work full time, I get to pump while there, so she gets expressed milk from dad. We had a hard time when I first went back to work, in mid-January, where she didn't want to take a bottle from daddy, but she's been over that for a while now, and eats much better for him. But she just doesn't seem to want to eat...I've been putting her to the breast every hour or so, but she'll only nurse for a few minutes, then pull away to make faces & play, or fall asleep. I've tried offering a bottle afterwards, both of EBM & formula, thinking maybe the breast didn't have a fast enough flow or something, but she's not any more interested in the bottle. I know I've got an adequate supply, when I pump at work I get 5-10oz per pump. What should I do if she just isn't interested in eating? How can I get her to gain weight if she won't eat? I wasn't concerned before, as she's always so happy, but the doctor really seemed concerned.
