I had to wean LO off of BF 3 weeks ago after having an emergency appendectomy. My breastmilk dried up completely after surgery, despite pumping and dumping. On BM LO was eating 2.5oz every 2 hours. Now that she is on formula, we were hoping to spread it out some, but she is taking 3oz every 2 hours. She is 16 weeks old. She gets 4oz at bedtime and in the middle of the night. She has terrible spit up issues (even while on BM) and it seems to be worse when she gets more formula. She also still wants to eat every 2.5 hours on 4oz.

Any advice? From what I have found, most babies are eating 6oz every 3-4 hours by now. Has anyone else had a LO that like to eat so often?

She is around 12.5 pounds now and is very short (always in 1%%).
