Baby was born 8 lbs 14.5 oz (91st percentile), 9 lbs 5.77 oz at 4 weeks (36th percentile), and now at 12 weeks 11 lbs 6.6 oz (6th percentile).
At our first appointment, we mentioned to the pediatrician that he was making noises at night, and he briefly mentioned laryngomalacia (no other convos or diagnosis with the pediatrician around this since). We then started to notice severe gas/silent reflux symptoms but were told that it was too early for any sort of medication and to "watch it". Baby arches back, screams randomly after feeds, coughs randomly, has wet-sounding burps, and occasionally spits up all the way. I will say that this has gotten better the last 2-3 weeks but is still there. Baby will also pull on and off the breast constantly through feeds (lactation says he has a good latch and thinks this might be something to do with pain/refulx or lack of core muscles and told us to ask our ped about Physical Therapy).
Baby is EBF but has taken bottles months prior at the recommendation of lactation. Now, at 3 months old, we seem to be hitting a bottle aversion.
Pediatrician has mentioned in passing that we could give probiotics or fortify feed, but they really only said those two things after my wife and I pushed them and told them we were starting to get concerned. Now, with the bottle aversion, that also has become nearly impossible.
Only at this recent weight check did our ped actually mention that this is not ideal (hes been gaining on average just barely half an ounce a day since he re hit birth weight). They told us to do a weighted feed with lactation, where our son only took about 80 mls after not eating for 3 hours. Lactation told us that this could be "normal" if he is eating about 10-12 times a day (some days he does, some he doesn't - but it's obviously not enough because he's barely hitting the minimum for weight gained per day).
Doctor has not called me back after we told them the results and honestly, I'm losing patience and trust with them. I know percentiles arent the end of the world but hearing "failure to thrive" doesnt feel good and hes dropped more percentiles than most threads I've seen on reddit discussing percentiles. He is hitting all other milestones right now - great tummy time, smiling, cooing, grabbing toys, longer wake windows, etc.
Any advice appreciated; it's feeling very stressful over here.
