I have a 6 week old baby boy, he has had issues since he was born with not gaining weight. He was born at 7 lb 4 oz. He went down to 6 12oz at discharge had severe jaundice that had required 2 seperate Bili treatments because it kept coming back and since then he hasn't been able to gain anything. He eats every 2-3 hours breastfeeding only but after last appointment my lactation comsultant weighed him before he fed and after and he latches perfect and swallows perfect he even ate for quite a long time and still gained basically nothing after eating. She said his Frenulum looks tight and he might be tongue tied so we have an appt with an ENT. He also has had issues with puking lots for his first few weeks after birth ( they thought pyloric stenosis because he's not gaining) now we have to give him little bits of formula after he breast feeds to try to.put on weight for him. My issue here is that now he screams and cries for hours every night to the point of not latching on at all or taking the bottle we use for his supplements. He has been not pooping much since we had to start doing formula with breastfeeding. I give him gas drops I even try the infant pain relief drops becausw he screams so hard he's completely red! I try his vibrating chair, baths, rocking, bouncing, tummy massages, bicycle leg pumps, etc. I don't know what to do anymore! I have switched from the formula thats closest to breas milk, I tried sensitive tummy kind, and now we are trying soy because the other 2 made him scream and cry in pain even more they even thought it was reflux at one point. I need some pointers ladies, I dont want to give up breast feeding but some nights I want to just cry because he goes hours screaming and won't feed right and I am only able to pump about 2 oz combined from both breasts after he eats and I cant pump all day in between feedings because hes always fussy and then I have a 3 yr old whos constantly needing me to follow her around. I need some kind of advice or tips because my lactation consultant is only in on certain days and I am so sad that my little man is crying like this I know he's not underfed because I watch him swallow at the breast and then takes his bottle after also but with this crying fits he has for hours and hours I get so tempted to give up. He never screamed like this before we introduced formula now hesbsuch an unhappy little guy im so sad about this!
