Going Swimming?

I was getting dressed this morning while my 2 year old son was sitting on the bed watching Mickey Mouse Clubhouse. I didn't think he was paying any attention to me, but clearly I was wrong. I put on a pair of bikini underwear, as opposed to the usual thong that I wear, and my son got really excited..."We're going to the pool?!" he said. LOL! I can't believe he knows the difference between my usual underwear, and what looked to him like the bottoms to my tankini! Guess I better be careful what I do around him from now on!
