So, I have eighteen children coming to a 4 yr olds party. So far we have got as far as a date (I think). Now we have the difficult bit of choosing a theme.
Castles / princesses / knights
or
Easter
For the castles on we could decorate crowns, and for the Easter one we could make Easter baskets/bags for all the easter eggs we find on an egg hunt.
Those activities don't fill 2 hours though. What else can I do?
