S.D.
most babies end up with the bald spot on their head, and their isn't anything that can be done about it. Once he starts moving around, the hair will grow back
With the reflux, i was just reading in what to expect the first year about that. if he cries while eating that is a sign. Spitting up isn't a sign. I never sat my kids up after eating. most of the time, they fall asleep, and go into the crib just after eating.
