DD is turning 1. We are having a party at a restaurant where they'll set up a kids tea etc and will clear out the conservatory for games / toys / an entertainer. We have a mixed age group of kids who would come- about 15, only 4 of them are 1+, most are around 2.5-4, and a couple are 6-7. I have no idea what to do to keep them entertained! Should I set up some toys? Or hire an entertainer? We also have a lot of friends who don't have kids so can't have the party at a soft play / dedicated kids venue. Help please!!
