My DS1 is 6 (7 in May) and has always had a tendancy to be very slight in build, however sfter a number of bugs he is now extremely skinny and underweight. He is as we speak in bed with yet another sickness bug, and he really can't afford to lose anymore weight. I don't dare weigh him as I think I will be very shocked, but I can tell from the bones sticking out of his body that it is severe :(
He isn't a great eater, very fussy, but got by and did have a few healthy food favourites. But he hasn't eaten a proper meal for weeks as he is always poorly.
I am at the end of my tether, and I am scared of my son getting seriously ill.
