Much to my astonishment, the healthy snacks are going down a storm! I replaced all the crisps, biscuits and squash with water, fresh fruit and veg and hummus and dips...................then stood back and waited for the moaning: there wasn't any! They all love the healthy stuff and I am feeling smug. Their teeth won't fall out-at least not for another 70 years or so, with any luck.
And if they do it won't be my fault.
