Alex's clothing issues.....

There is something Alex has been doing for a few months that has been driving me crazy!! The boy has clothing issues! He is constantly changing his clothes! He gets home from school and changes both his shirt and shorts/pants....OK, no problem, he's sick of wearing that all day....but...then he'll change again...and again.....3 or 4 sets of clothes. When they clothes come off, they can go anywhere, on the floor, on the bed, in my room on the floor, sometimes back in the drawer all balled up and wrinkled and sometimes, rarely, in the hamper! I'm washing clothes like crazy - I think Bill and I together did 4 or 5 loads on Sunday, and I do usually a load every other day during the week! I don't know what is clean or dirty and therefore I just wash them! Also...he puts on swim shirts...and they fit...well..snugly....he is in this photo with sleep pants and a swimming shirt! He also likes to go into Ben's room and put his clothes on for kicks. And, while doing so, will dump all clothes out of Ben's dresser drawers onto the floor! And Halloween costumes! He's really into them - - wore an old costume of Ben's, think it was a star wars clone uniform - all day!!! I hope this phase stops soon....well, though I wonder what crazy thing will replace the clothing issue!!
