DD eats loads at the moment too.
She has pudding every day, yogurts, fruit, ice-cream (those mini magnums work well), chocolate mousse (v messy!!), jam tarts/other cakes (Mr Kipling-style small ones are good if you don't want big cakes/portions), biscuits, etc. Anything we have in & the boys are eating & she'll eat basically 
Have spoken to DS2's school, the Head may call the buses to bring the kids home early if it's looking like it will turn serious.
I'm not sure about this as a plan as the bus route can take a long time.
So, it starts snowing, Head assesses, decides it's worth calling buses into action, drivers & escorts appear (presumably they aren't actually at school all day?), load up the kids, set off on route...snow gets worse/roads get worse as snow continues. 45 mins later they phone us stuck 
At least, in theory, we can walk to DS1's school and sledge him home again - well DH has said he could do that, i don't fancy it with DD.
Also, meant to be collecting our babysitter from her workplace (as she doesn't drive) at 6pm to get her here in time for us to go out to a dinner-work-thing. Thinking that may all get cancelled.
