Hi Chasmom,
Thanks for your advice - yesterday I decided to cut back on formula and you're right, I think I was pushing too much in and he must have decided he wants less formula. I've been thrown by the recommended amount of formula and also my ped. told me that I wasn't overfeeding him. But yesterday morning, he took about 3-4 oz, then when I gave him some more about 30 mins later, he threw up. Since then, I've stopped when he's stopped and cut the bedtime bottle by 2oz and so far, so good, just a tiny bit more similar to reflux than full-on projectile vomming. I've noticed that he takes his solids much better than some of my friends' babies, so his tummy must be full and I'm trying to overstuff it! I guess my instinct was that I was over-feeding, but my ped. made me feel stupid really....I should trust my mummy instincts more!
Thanks so much, hopefully he'll keep his food down this week.
