DS has visibly shrunk in the last few weeks and he was quite thin to start with. He's only lost 1kg, but his appetite has gone down too.
I'm not sure whether this is because of all the extra running around and walking to and from school or I should be worried. We've got a GP apt at the end of next week just in case he loses any more weight or his appetite doesn't pick up.
This is a child who has never failed to finish a meal before and always crept up the weight charts bit by bit. He didn't even lose weight as a newborn.
