My girls originally got this toy as a gift.  It came with a single unit and all the Upper Case letters of the alphabet.  It was an instant hit and helped to keep the girls busy while I was preparing meals.

While shopping in the store the girls discovered that there was an expansion pack that included all of the Lower Case letters!  Of course we had to buy it.  So now we have all the Upper Case and Lower Case letters on the fridge.  Ok great in the fact that the kids can learn their letters, not so great in the fact that these things take up A LOT of room on the fridge.  They also tend to gravitate...
