My son is 14 weeks tomorrow. All day Friday he was taking 5oz every 3-4hrs (it was 4oz every 2 hours, and he finally went up..or so I thought). Friday night, after he drank the bottle before his bedtime bottle, he threw up all over himself about 20-30 minutes later. He had burped fine so we were confused, and he's had a little cough (that I took him in for, and ended up being nothing serious) so we thought maybe he threw up from that. Then, 20 minutes after his bedtime bottle and a good burp..almost projectile-like vomit again. I thought maybe we were overfeeding with the extra oz, so I brought it back to 4oz. However, since yesterday morning he hasn't finished a 4oz bottle at any feeding. Some feedings he will only want 2oz...even after 3-4 hours!? I'm scared he'll get dehydrated, but he is still wetting his diapers and his soft spot feels fine. He has had no fever and has been in a great mood, even after puking those 2 times he smiled. I'm just really confused. If he keeps this up, I'm calling the pediatrician first thing tomorrow..but is this normal?
