DS best friend is moving house in the new year 3 hours away 
He is coming for the day on friday and I really want the boys to have a great time but his friend is CMPI and I'm sure his mum does not want him ill over xmas! Normal playdates haven't been a problem so far tbh.
Boys being boys they love their food so any suggestions of the best biscuits/ chocs/cakes/ ice cream equivilents I could buy? I really want them to relax and have what they want without me having to deny him anything iyswim?
Or is it better for me to make a cake and what butter alternative is best?
