Eryn (she's 4 1/2) got some for Christmas. I keep hearing hubby and my oldest "there's moon sand all over the floor."
She has it in her bed, too, I guess. There's so much stuff on the floor.............toys everywhere, the moon sand is the last thing I'm worrying about! LOL
Anyway, she seems to like it. My oldest (she's almost 13) was playing with it, too.
