Whose Pajamas Are These?

My little Logan is growing so fast and is not so little anymore. And my Ally is so tiny that she has clothes that are meant for a 2 year old.
The other night I couldn't find any clean blanket sleepers for Logan. My house is a little chilly at night so I like to make sure Logan has warm pajamas. So I had the idea that with all the sleepers that are in Ally's drawers, there must be atleast 1 that is gender neutral. (Most of the things in Ally's drawers and closets are very pink, purple, flowery or girly)
I finally found a mint green sleeper. Definitely something a boy could wear. (I guess technically he could have wore any of them)
I called Logan to change him into pajamas and he looked confused. He pointed at the sleeper and said, Mine? And then he thought and said, Ally's? I just reassured him that it was okay and changed him.
I really thought that he would be completely oblivious to which pajamas he was wearing. But he had to show me he's smarter than I think.
