Here's a trick to pull out of your rainy-day-bag, or when you absolutely need something to do with the kids: peanutbutter play-dough! I suggest doing this only as a treat as you are practically handing your kids candy, but the delectible, moldable stuff is sure to be a hit and is as easy as it is entertaining.
Simply put a large spoonful of creamy peanutbutter into a bowl with equal amounts of powdered sugar and flour. Work it all together using your hands - or letting the kids do so - until the peanut butter is thick and still soft and moldable but no longer sticky, adding more sugar or flour as needed.
This works best with truly creamy peanut butter, and therefore not as well with the natural stuff. Also,you can omit either the sugar or flour if desired. I've never tried to do this with a substitute such as almond butter, so I can't vouch for that... but if your child has an allergy to peanuts, it might be worth a try. Research and recommendations as to at what age you should allow peanutbutter into your child's diet varies, so consult with your pediatrician if you aren't sure.
