Birthday parties

Kids love cake. the tradition I have started with each child is:
1. to ask the children who is having a special day today (usually we know who it is as they have brought in cake)
2. the child stands next to me and we ask the group which song we need to sing
3. the group sings happy birthday
4. we give them their age in claps (ie. 4 claps) and then 1 to grow next year (5 claps total).
5. we share cake and then say thank you to the birthday child.
