Even though having two kids under two is very demanding, they do play together and that is a good thing. They even entertain each other and that gives Mommy a break from their demands for snatches of time throughout the day, and that is a VERY good thing.
Little brother keeps a close eye on big sister and tries to copy her no matter what she is doing. I think this chair might be a school bus and she is the driver. Or maybe it is a garbage truck and she is doing her rounds. Little brother is the gofer and has to throw the bins in the truck while she sits and drives. Seems fair to me!
They both seem quite happy with the arrangement. Such a cute pair!
