OK, now just understand that this party is for YOU, not your daughter, right? She will probably either sleep through it or be so overwhelmed by it that she will have a huge meltdown. This party is for your family to celebrate the addition of a new member of the family. That being said... Yes, get a bouncy house and have a few crafty activities set up for the older ones. Playdoh works well for all ages, have lots of cookie cutters and standard kitchen implements for them to make shapes, etc. pinatas are always fun. It is very important that you have a person who can attend to the birthday girls needs at all times. She will not know what is going on and you will be busy with hostess duties, so she will need somebody to find her binky, make sure she is not eating the balloons, hold her finger while she walks around, etc. Have a blast!
