My four month old baby spits up quit a lot, getting worse at about 3 months old. I counted 8 times in two hours once. He doesn't ever NOT spit up after a feeding. But he does not seem in any distress, he's generally a happy baby. Also we think he is still gaining weight, and is pooping/peeing regularly, etc. His 4 month check up is next week, but I wanted to get other mother's advice on this. I have cut way back on dairy because I think it gives him gas. I go through tons of laundry because of this and it gets all over everything! It's very inconvenient!
