My son is 18 weeks old (4.5 months) and at his 2 month check he was 12 lbs. At his 4 month check he was 12 lbs 6 ounces. He has grown length wise, but his head circumference dropped a little on the curve and he has gone from the 10th percentile in weight to the 5th. He eats 23-27 ozs a day of breast milk and the LC at his doctors office said he needs at least 33 a day just to maintain his weight. He is gets pumped milk only so I expected him to be a little smaller than normal like his sister was/is but not this much.
The doctor had me start harvesting the fat from all my stored milk but oops...I have a high amount of lipase enzyme and he will not touch the stored milk! So we are not having to supplement with a high cal formula in his BM bottles but he is HATING the taste. It takes about an hour just to get 2 ounces of milk in him right now so every waking moment of his day is spent trying to get him to eat. We saw a feeding specialist who thinks his jaw is set a bit further back than normal which may make it hard for him to eat (which I don't totally believe since he was gaining an ounce a day up until he was 2 months old). He has reflux which I thought was under control with my diet but the doctor thinks it may not be since he crunches and fusses/pain cries in the middle of feedings...usually after eating only an ounce.
I'm starting to realize he is SUPER gassy and once he gets out a huge burp, I can get an extra ounce in him. His doctor is going to be referring him to a pediatric GI specialist (2.5 hours away since thats the closes one!) so needless to say I'm scared for him. We were given a Habermen special needs feeder which cuts down on the air getting in him, but he has a really hard time getting more than an ounce an hour out of the darn thing. he does great with dr. brown standard bottles with getting milk out efficiently, but he is getting tons of air too (which I'm starting to think is the main issue with not getting enough to eat...if theres too much air, theres no room for food).
The biggest issue is he has a hard time burping when he needs to so he is starved but cries when he tries to eat. Its really heart breaking So my question to you all is have any of you dealt with this? And is there anyway to get him to take the formula supplement in his breast milk without fussing so much? The dr. wants 3/4 of a tsp per 2 oz of breast milk but he tastes it, so I've started doing 3/4 of a tsp per 3 oz...he takes it but not really willingly. I'm going to have to go down to 3/4 per 4 oz of BM but since he only eats 2 oz an hour, I run the risk of wasting my milk. UGH! I'm so scared and fed up and praying he has put on weight by his weight check next week...
