If I may I would like to give you some thoughts about kid magic. I call kid shows and this is including birthday parties, I call them family shows.
Because the kids love to get involved with the show and watch the show. The parents and adults like to watch their kids get involved with the show.
If I may give a few thoughts about this subject. My Dad (the late Billy Bishop) was a family show entertainer. He started doing birthday parties and shows for the elks club etc. Then later performed in Vaudeville in what was called "Family Time."
Al Baker was the same kind of an entertainer.
Later my Dad got into doing early television and Night clubs. The night clubs were different than the night club/comedy club of today. Because in the old days the night club acts at the class night clubs were class. That is that a family could take the kids and they would enjoy the show.
My Dads (and my) magic material was and is about the same if we would do an adult banquet or a birthday party. The only difference is the audience.
If I may add this about performance attitude, that is I treat kids like adults when doing a show and adults like kids (in a way). So as an audience they sort of meet in the middle as a group you might say.
Here is a list of magic effects for stand up family shows that I enjoy. Hydrostatic glass, misers dream, Chinese sticks, rice bowls, linking rings, knotted silks, Jimmy Stoppard's billiard Ball routine, card sword, king monte, split deck, mental epic, brainwave deck, the phantom tube etc.
Chop chop used the chop cup as an encore for his stand up night club act. Galli Galli used the card in balloon as an encore and Roy Benson used a stand up closer called the Benson Bowl.
Jack Gwynne closed with the torn and restore magazine page. All would be great magic for a family show.
There is more of this in books like Tarbell, The Mark Wilson Course in magic, Greater Magic, Magic With Faucett Ross, The Life and Magic Of Billy Bishop by Glenn Bishop and published by David Charvet.
Al Schneider's DVD Vol 4 has some great stand up routines including a great coin routine using 3 stunning coin vanishes and a coin tray, and the best zombie routine I have ever seen.

I hope this helps.
