I have a 4mth old baby girl who had been very spewy since birth. Most of the time she doesn't seem to be distressed by it but she throws up so much during the day that I worry that she isn't keeping any of my milk down. I need to change her bib about 3 times between each feed just to try and keep her dry. She is starting to get a rash on her neck from being wet all the time. She is exclusivly breast fed at the moment. Is there anything I can give her to help her keep her food down and stop her throwing up so much?
