DS has been off his food for about a week/10 days. He has always had a healthy appetite but is now refusing to eat many of his favourite foods and is existing on a diet of bread and yoghurt although tonight he was even refusing bread. We were on holiday for a few days so he's possibly unsettled but his appetite was going even before then. I know the general rule is not to worry if they seem happy and alert and are still drinking (which he is) but just so worried and don't understand why he is suddenly so fussy. He was teething last week and also had hand and foot disease (we think) so could be linked to that. Can anyone shed any light? So worried.
