Since you have some time and you seem to be happy with the quality of JC Penney in the past, why don't you go to AC Moore or another large craft store and get a wooden #1. You can paint it whatever color you like, that might match her dress or outfit then have her hold it.
You can also buy stencils and cut out a foam number if that is easier or you can't find a wooden one.
We moms have to get creative!
Good luck.
