My 6 month old baby is violently sick shortly after eating mashed banana. This has happened on 2 separate occassions now and I am quite worried. He is violently sick repetitively for upto 7 hours. The first occassion I took my baby to hospital, but they just said he might not be ready for weening yet.Now though, he is 6 months old and trying small tasters of other foods, except for banana where he gets sick. He once did the same thing with petit- filous.Has this happened to anyone else?
