I just finish my daughter's BP last week. My daughter is K3 and she also give out about 20+invitation card to her classmates. I also write down to call back to confirm. Finally about 4 call back cannot come and then 4 already give present and write cannot come.
only 4-5 call me and confirm they can come. Finally, total about 8-9 come. So I prepare more gifts and for the food, I only count the adults. As my club house is close to the shopping centre, so I buy some food downstairs immediately.
Actually, it is quite headache to prepare BP, but my daughter is very very happy esp. for her classmates come
