Who needs toys when you have a sock? Or a flashlight?
My son spent at least a half hour tonight flinging a sock up in the air, running forward (arms flailing) and attempting to catch it while it was moving in opposite direction, all the while singing some rap-type thing about "I win I win yeah yeah yeah." That was after the birthday party he threw for me (no, it's not my birthday, but he wanted it to be, so it was), complete with flashlight. Don't ask me the connection between birthday and flashlight, but we had fun making shadow puppets on the ceiling. Before he went to bed, he played "hide the sock on Mommy" several times, a game in which he very cleverly placed sock in sneaky (but strangely obvious) locations and I had to "find" it.
Who needs tv when you have a 4-year-old boy?
