We don't get the Play-Doh out too often, but when we do... The kids are very busy for a good two hours straight. Today it coincided with me filling about 5 or 6 bags of crap in my basement to be given away. Happy New Year.
My niece and nephew played with play doh at my house and there was less and less every time I looked at it. Then I looked at my dog who was happily munching. They made it into dog bones for the dogs.
My kids are obsessed with playdough ... a two hour stretch however, is unheard of here! Then again, mine are 3.5 and almost 2 ;)
