DS is 5 months and for the past week or so, has seem very disinterested in eating. He gets breast-milk, formula and solids, and none of these seem to interest him much. He used to LOVE food. Now it's like he'd eat the food, but only enough to not be hungry. To put it in perspective, he is still eating about 5 feedings of breastmilk and formula a day (probably around 4 ounces each time) + 2 meals of solids (again, 1 - 2 ounces a time). On the other hand, he is visibly less chubby and also doesn't produce as much "output". I talked to my doctor and all I got was "he'll eat when he is hungry". Being a FTM, of course now I'm paranoid and meal time has become rather stressful because I'm constantly monitoring how much he eats.
