Im the nanny for a 14yo boy and I have noticed that he is getting quite thin. All the teenage boys I have ever nannied for (or been related too) have been fridge hoovers who eat 24/7 and never thin out. I have noticed him not eating on occasion but he has always had an excuse for.I was wondering whether it is a boy thing? Being an ex bulimic I am getting concerned. Any advice from mums with teenage boys??
