TOILET FASCINATION

What is it with toddlers and toilets? Andrew is fascinated with the toilet. Oh no, not going potty in the toilet. He wants to stick his hands in it and play in the toilet. Absolutely disgusting! He sticks anything and everything he can in the toilet and will even try to get his hands in there if you are going potty yourself. Today I had to throw a toothbrush away. I guess he wanted to clean the toilet. It drives me batty. Why?
