Re: Need Support/Advice
Welcome! Looking at this chart for breastfed baby boys: http://www.kellymom.com/babyconcerns/growth/chart2.html I am thinking that your baby was born on the smaller side, shot up in his first few weeks and then kind of fell back to a percentile roughly equivalent to the one he was born at. It's not necessarily a growth curve that indicates any sort of problem. Babies follow very individual curves, and as long as a baby appears happy and healthy and continues to grow, there's no reason to worry just because the baby doesn't follow the "ideal" curve on the chart.
If your baby is typically taking in around 3 oz at a feeding, I think there's no reason to be concerned about your supply or about your baby's feeding frequency (which sounds very normal, BTW). However, I have to wonder about those urate crystals. IIRC, they can be a sign of inadequate fluid intake, and therefore my gut feeling is that you might want to play this one on the safe side and get a rental professional baby scale, and collect several days worth of data on your baby's intake during nursing sessions by doing weigh-feed-weigh tests. I don't know one single thing about low pH, so maybe I am totally out to lunch here...
