My son is 14 months old and until a couple days ago was nursing three times a day: upon waking up in the morning, before naptime, and before bedtime. A couple weeks ago he started throwing up, almost exclusively at night but sometimes when he first woke up. At first we assumed it was a virus, but it kept going on and on. A pediatrician suggested that it was reflux and that we shouldn't give him any food before bed. I cut the bedtime nursing and the vomiting at night stopped. However, he continues to throw up in the morning, always within half an hour of nursing. He's never thrown up after his midday nursing session.
Is it possible that he's grown sensitive to breast milk? My diet hasn't changed at all. Or maybe he can't tolerate that much liquid in his stomach? Any ideas or experience with this?
