So DS had his 15 month well baby checkup today. Everything is fine except....he hasn't gained any weight since the last time I brought him in. In fact, one of the times I took him in recently when he was sick he weighed 19 lbs 15 oz and today he only weighed 19 lbs 11 oz. So he has now dropped from the 3-5 percentile to 1.53%. His height and head circumference are good. He is 30.75 inches (30.97%) and head is 18.25 inches (23.17%). But the weight is pathetic. Now we have to try to supplement with Pediasure which is expensive. I am not optimistic about that working because the whole problem is he hardly drinks anything during the day (e.g. milk, which is where a lot of calories would come from). We are off bottles completely and sometimes he will drink a good amount of milk at dinner time out of his sippy but I would bet he's only getting at most 6 oz on a good day and he should be getting closer to 18-20 I bet. He's always been small and has never been above 5% weight wise but this has me concerned. I really expected that he would be closer to 21 pounds.
I'm really frustrated and feel like a bad mother. I just don't know what to do. He eats pretty well, but I guess we need to try more high calorie/high fat/high protein foods. I'm just not sure what else to give him besides what I already do. He is picky sometimes, especially at home. My neighbor's son is 6 weeks younger than DS and weighs 23 lbs. The doctor said DS may just be a small kid, but they do get concerned if their weight drops below the 3-5 percentile and that is where we are at. I just feel like crying. He's healthy, he's happy, he's developmentally on track, but I worry that he's starving and not getting the fat he needs for proper brain development. I can't force him to eat or drink so I'm sort of at a loss.
I bought some shorts for him this weekend in 12 month size and put some on him Sunday and they fell down because his waist is so small. Ridiculous. I'm racking my brain trying to figure out what I can do. Ladies, if you have any ideas as to how I can help my son gain weight, I would appreciate any suggestions.
