I've somehow volunteered to host some festivities next week for a day - there will be a 9yo (who is very mature for his age but equally lovely playing the much younger other attendees and also has a bedroom to escape to if he needs some quiet!), 4yo, three 2yos and a 9mo. The 9mo and one of the 2yo will each have a parent with them for the duration, the other 4 I will be responsible for. The other adults are only likely to be around for a couple of hours until early afternoon.
I'm thinking of putting on the Polar Express from about 3pm with some popcorn, to see them through til dinner time and then 4yo and 2yo will go home leaving me with just my own two 
Any ideas what festive activities I can do for the morning/early afternoon? I'm not very good at crafts but am willing to give it a go if anyone has any specific ideas!
