I also called the lactation consultant that is in Ramona and told her what was going on. She gave me 3 things to do:
-eliminate ALL dairy in my diet for a week to see if he spits up less (because Nick is lactose intolerant he may be as well)
-while nursing compress my breast to make him get more milk/suck/swallow more since I told her I don't hear him swallowing the entire time he is nursing
-after he is done nursing, pump on the same side he just nursed to get out any extra hindmilk he hasn't sucked out and feed it to him via a bottle immediately to help him get more "Fatty good stuff"
She also said because he doesn't have frequent bowel movements doing these things may help with that as well and if we start seeing them increase in frequency to once every other day or so we know we are on the right track. In a week she wants me to call back and let her know how it's going and if we are still getting lots of spit up then she said maybe just maybe we would talk about solids (I didn't tell her about the asking for a reflux med yet).
I looked up the WHO growth charts and unfortunately they don't bump him up percentage-wise in weight. I plotted each of his lengths/weights and the percentiles have gone down each time:
Birth 8lb2oz (75%) 21in (95%)
3 weeks 8lb10oz (35%) 22in (85%)
6 weeks 9lb12oz (18%)
2 months 10lb10oz (15%) 23.75in (80%)
4 months 11lb13oz (less than 2%)>
I'll keep you updated on how the new suggestions from the LC go, no dairy is going to be interesting for me but if it fixes his spit up than I'm good with it!
