Yes I'm breastfeeding but I mostly pump, I was overfeeding him without knowing that's why he is so big but I've cut him back and he's gaining the right amount per day now lol he was 8.4 at birth dropped to 7.11 it scared me so I fed him like crazy to get his weight up. His 2 week apt the doc said he was chunky butt and I could feed him up to 6 oz she was wrong that was way to much for his age. At 5 wks he was 14.6 lbs, we saw a different doctor who told us 4 oz every 3-4hrs since doing that he only gained an oz a day before he was gaining 3oz a day! :/ makes me sad he was tiny one week and huge the next!
