So I figure at 4 1/2 it is time for Hotrod to start having some chores and responsibilities around the house. And being a boy I want him to not differentiate between tasks based on perceived stereotypes.
So one of his new chores is to help with the laundry. His favorite parts is separating out the whites to fold. His job is to get all the socks and underwear and separate into mom's, dad's and his. Now of course this is not a straight forward task, it's more of a process. Part of this process is making a train out of the sock.
