Anyone got any immune system boosts? My three dc have been on and off ill since Christmas. We have had sick bugs, flu, sore throats, and now we're on about 3rd bout of cold/sore throats, and they're not even at school. I can't take it anymore. It's messing with my sanity. Does anyone have any ideas on how to build up better immunity? They are pretty good at eating veg and fruit, and they're not too fussy, although don't always eat everything I eat, but that's a different thread.
