i have a 10 day old who cluster feeds 3-4 times per day and spends the rest of the time soundly asleep. So last night he worked himself up into a more than normal feeding frenzy and kept acting like he was STARVING! I already can't keep up with him on breast milk, so I'm supplementing with formula. He's above his birthweight, but is still only 7 lbs 2 oz or so. When I feed the little piglet, I have to stop him to burp as he does guzzle as fast as he can. But last night he just kept eating until he threw it all back up during his couple hour or so feeding frenzy. He was fussy and went through a few poopy diapers, so maybe he had gas too? He was back to his normal feeding routine this morning. Any ideas on what caused him to overeat? How do I keep him from doing this?
