The boys have been learning (among other things) to clean up after themselves.
There are three primary sets of toys dominating play time right now: a train set (gift from gigi and ryan) and legos (gift from david and maryanne), and a set of "cut-able" wooden vegetables (gift from Katie's mom Colleen).
When finished, Isaac and Will are equally passionate about carefully storing every piece in its designated container, and meticulous about quickly correcting any errors made in the cleanup process.
The boxes are carefully stored on the shelf in the exact same locations.
Also high on the list right now is vacuuming and doing dishes (now if I can just get them to sew fancy basketball shoes I'll be I'll set).
Of course Isaac's favorite projects always involve some reason to use the shop-vac.
