DS is 8, he has had a horrible D & V bug which lasted for 5 days and he is completely washed out. There's not much meat on his bones as it is and he has lost about half a stone and looks awful. Any suggestions on how to help him get his strength back and put a bit of weight on him? He's a very picky eater at the best of times but I'm actually getting worried about how thin he is. I'm thinking a little and often may be better to get him started as he hasn't eaten anything solid since Monday night?
