My son is 6 months old born on time not premature weighs 16 pounds right now. He was eating well and gaining weight well until 6 weeks of age, then everything went haywire. I was breastfeeding exclusively and was having problems. For many months I though thats how it was supposed to be or that he didn't like my milk or that I didn't have enough. When I switched to bottle, I saw that he ate and still till this date eats 1-2 oz quickly and then the struggle begins. I'm concerned that this medication is not working for him. After that first ounce he just either nibbles on the nipple of the bottle or pushes the bottle away or cries. Trying to get him to eat 4 oz is such a struggle. Which I think he should be eating more at this age. It usually takes one full hour and sometimes I have to wait until he falls asleep to feed him. The only times that its not struggle to feed him is when he is sleeping. I am usually able to get into him within 24 hours approximately 23 oz. I am worried that he is not eating enough. Any help would be greatly appreciated
