So my baby was born at 45th percentile and dropped as they do initially but by 3 weeks was slowly back up to 20th and then 30th by 4 weeks. And since then it's been downhill. Every month he's been dropping more and now at 4 months he's at the 7th percentile. He's tiny and often sucks his hand or rarely cries for milk. He's exclusively breastfed but I've offered formula and expressed milk. He refuses the bottle or tries for a good few minutes and barely gets out 10ml. When starving he'll get out an oz or two max. Sometimes he takes it via syringe. I don't know what to do as he's definitely hungry but also seems like he's used to it now and doesn't fuss much. I've been to check his latch etc and everyone says it's ok but I feel like there may be a lip tie. Just wondering if anyone had anything similar or some words of encouragement. I feel like a total failure and really have tried to get his weight up. He's a very tall baby too so it isn't that he's just petite.
