Simeon is apparently a very smart little boy (you already knew that though, didn't you?) who can imitate things he sees after only one time. Like the time when we used the plunger on the toilet.
So, I went up stairs and found Simeon, binky in his mouth and the brand new (thank God) toilet bowl brush in his hand. He was 'plunging' the toilet and flushing it each time. Elianna fortunately was willing to run and get me the camera so I could capture the moment. Which I did. That 'moment capture' was immediately followed with clarifying for my little handy man that toilets are not for playing and a new rule in the house - keep the bathroom door closed :)
