Suddenly realised DD's birthday is only 2 weeks away. Have hurridly booked the village hall and need to get the invites out. There will be 20-25 kids from 2.5 to 5 (mostly 3-4). Trying to think about what to do with them for 2 hours. Don't want the expense of an entertainer etc. Have come up with pass the parcel and musical hats (plus the usual variations) - anyone got any other suggestions for this age group or I'm going to be wrapping a lot of parcels!
