I saw some kid's events during my trip, I think some of the them can be reference for our birthday party.
Besides the stage, does it possible to set up different activities in the cornor, such as facial dressing, if any mami can handle it, the kids can come to make up as a flower, a mokey, a cat, etc.
Another conron can prepare a few pieces of differenc color 絲巾. Just demo to the kid to flow it in the air randomly, and the kid to catch them, the effect is good, easier to handle then flow a ball.
Also, if the stage is big enough, we can also just bring one toy from each kid to share with other on the day. They the kids can play themselves with many different toys.
Of course we have a story corner, by Rosan right. But it is hardly to draw all kids at the same time, I would suggest you may repeat in every hour. And all together you may talk 2-3 times. Does it too hard? Besides, I have following animals, crocodile, Penda, chicken, Bear, cow, frog, rabbit, mickey. Any help?
Anyway, all these are suggestions, and relay on is there any mami's hand available.
