My son will be 5 months old at the end of this month when he was born he had a hard time latching on but finally did it continued to be a problem he would only nurse for 3-5 min total and cried all the time. I stopped BF when he was 1 month old because I thought I wasn't making enough. After that we tried several different formulas and he still wasn't very interested in eating and cried like he was in pain all the time, his ped sent us to a GI doctor where he was diagnosed with a milk protein allergy and reflux after trying several other 'special' formulas he finally ended up on Elecare and also takes Prevacid for reflux his crying has since gotten much better but he still won't eat. He will suck down 2-3 oz and then push the bottle out of his mouth and jerk his head from side to side and fights you and cries if you try to make him eat any more. Sometimes I can put his passy in and let him suck on it for a few min and pull it out mid suck and put his bottle back in and he will eat 1/2-1 oz more, I try this trick at least 3 times every bottle. Sometimes he will eat more most of the time he won't. He eats every 4 hours and even after eating only 2-3 oz he will not cry like he's hungry at all. He only averages about 18 oz per day and his weight gain is very slow he has NOT been diagnosed failure to thrive but he isn't gaining weight quite like he should. I have never seen a baby fight you so much not to eat a bottle (sometimes he will eat ok but most every bottle is a fight and maybe drinks one 5 oz bottle a day) and I have never seen a baby just not hungry like this. I have noticed and I don't know if this has anything to do with it that when he stops drinking he will wiggle around and sometimes poops or farts, I know the sucking reflex stimulates things to move but I wouldn't think it would make him just not hungry. (If you saw him eat a bottle and stop you would think its a reflex thing like he doesn't like sucking but he takes his passy just fine) Has anyone else experienced this or have any clue why he doesn't want to eat? I am at a loss and everything the doctor does is a temp fix and he goes right back to not wanting to eat after a couple of days. We are going in on Monday so the doctor can observe him while he eats but I wanted to see if anyone else had any suggestions or thoughts. Also we have tried many different brands of bottles and nipples and tried all nipple flows it's the same thing with them all.
I think that going to the doctor and having his feeding observed is the best route to take. He might still have a lot of reflux issues even though you have the milk/soy protein intolerance thing figured out and he's on meds. He may need a different dose of medication and he may even just be afraid to eat more out of thinking a full tummy= hurting. Big hugs momma, and I hope you get it figured out soon! My niece has milk/ soy protein intolerance too and GERD and had to have her omeprazole dose adjusted four or five times before they found the dosage that worked best for her.
