I have posted in these parts before about my DSS. To cut long things short, he is 6, noticeably small for his age, and skinny, but not worryingly so I don't think. He come to us every weekend and during school holidays.
The issue is that when he stays with DP and I - he does not eat, or eats very little. And appears to have some kind of eating disorder.
When presented with food, he will gag, vomit, take tiny bites, say his head hurts, sit and cry, or make excuses to leave the table (usually needing to use the toilet). This happens at every meal time.
Last night things came to a head, when he has a full blown meltdown and then asked to go home to his mum. He went to bed having not eaten at all, for probably the best part of 12 hours. His mum denies there is a problem and will not hear what DP has to say, although she admits that she is not present during mealtimes (her mother is). Also no one seems to be monitoring what, if anything, he eats at school.
What can be done here? This is also having an impact on the other children in the house as they have to witness the unpleasantness each time, and it is causing a great strain. We are due to have him for the Christmas holidays and I am dreading the battle.
