Hi, My 1 yr old son keeps being sick for no apparent reason, this has been going on for months. There doesn t seem to be a pattern to his sickness, it is mostly at meal times but not every meal and not every day, sometimes when he is sick at mealtimes we clean him up and he tucks into his food again unfazed. What could be the cause of this? He is generally very healthy, only the usual coughs and colds that all kids seem to get.
