Waving Mystery Solved

Owen used to wave "bye-bye" all the time while in daycare. Since the summer started he has stopped. We were always curious as to why, but we think we figured it out. Today, on the way to Owen's playdate, Owen had to put on his jacket because it was raining. As soon as he put it on, he started to wave. When we got to the playdate he waved again as the jacket was removed. Mommy thinks Owen equates waving with the jacket. At daycare he always used a jacket because it was cooler (Owen waved). Since school got out, we hardly used a jacket since it is warmer (Owen stopped waving). Interesting....
