If your Daughter's plan is to make a cast of her Belly you may want to try plaster instead.......I personally could not have sat still(think frequent bathroom trips... )long enough for mache to dry when I was pregnant....Just a thought, good luck.....those "Baby Belly" casts are pretty darn cool, the first time I saw one being made was on an episode of The Learning Channel's "A Baby Story".....Perhaps you can check the TLC website.-Kristen
