Hi,
My 3 year old son became ill and started projectile vomiting on 2/12 . It subsided on 2/13 and then he started again on 2/14. At which point our 6 year and my husband and I came down with the same thing. It passed for my husband , myself and our 6 year old 2/15 but our 3 year old still has this every night. We are very concerned. We have an appointment with the pediatrician in the morning but wondering what this could be ?
