Plaster + 7 month old = Pain in the butt!

My mother-in-law got us this cute ornament keepsake--its plaster, and you make an imprint of your child's hand. Yeah, sounds cute. But has anyone ever TRIED to do this with a baby? Garrett thought it was great fun . . . he squished it in his fingers (that made a WONDERFUL imprint, let me tell you), tried to eat it, and attempted to "splash" in it. I finally gave up and made one of his foot. :-D Maybe next year it will be easier. But I don't recommend it with a baby!
