We found out Lizzy loves to pop balloons. I was cleaning out some crafting supplies I had and found a bag of shutterfly balloons from a shutterfly party package I got .... Lizzy saw these and immediately wanted me to blow them up.... I did and then she immediately wanted to pop them! I let her pop balloons before using a push pin so again she used a push pin to pop these balloons. I'm not sure if this is good or not she she sure enjoys it. I'm sure her up coming birthday will be filled with lots of balloon popping!
