I am not sure if I can be of help but I have some cheapy stamps that I got from a brand called Bang on the Door, and the Girl is called Groovy Chick, I got them in the UK so I am not sure if they are available State side if that is where you are.
They are aimed at a young age group and have a whole range of things from bedding to clothes.
This is the link to their official website which has some neat things for kids to do etc

this link from a shop in the UK but should give you an idea of what the stamps are like if you can find them.
