She's only been back at school for a few days and she's already got a cold - plus she's struggling to eat well atm as one of her front teeth fell out a couple of weeks ago and the one is very wobbly.
Anyway, what I really wanted to ask is if there is any way of boosting her immune system? I give vitamins from September onwards but she always has colds, coughs etc and had a lot of time off school last year.
