Hugs hon- all the spewing is so hard to deal with!

It sounds like you really need to work out what the cause of his throwing up is. He could have reflux, he might not agree with the formula, or he could just be a chucky baby. Before you change formula again, I would try to eliminate the other two. As you probably know, changing formula is hard on their bodies, so leave that until last. I would do two things. First, having the dr check him out for reflux- if its bad, they can give him medicine for it. Second, I would try a little formula thickener. Karicare makes one and it just makes the formula less watery and can help babies who are just naturally chucky keep it down a bit better.

If you don't have success with either of these (and your dr/mchn has no other suggestions), then it might be time to look at a different formula. Maybe a HA one?? I don't know what would be the best formula- best to take advice from dr/mchn on that one.

Good luck and I sympathise with all the laundry you are inevitably doing!
