9 month checkup

I am so worried about Ian because at his 9 month checkup he hadn't gained any weight. He is only in the 12th percentile for his weight. He is in the 84th percentile for his height. I don't think anything is wrong with my milk or anything like that, I think he has a small appetite. We are lucky to get him to drink 4 or 5 ozs of milk at a time. He should be drinking at least 6 ozs at each feeding. Plus, he only eats about a half of a jar of baby food at at time. He has been eating the same amount for probably the last four months. I think the kids has to start eating more so he can gain some chubbies.
