When's your most productive time of day? Mine happens to be the two hours after my coffee in the morning (go figure). So as soon as that happened, I pulled out an old cardboard box we weren't using and cut it into three long strips. From there I used packing tape to attach the strips together, and set up a race track in the living room. It's not pretty, but the kids don't notice!
I find if I get the kids set up with something that will occupy them in the morning, I will have time to get myself set up for the day- dinner prepped, laundry in the machine, nurse the baby and- gasp- possibly a shower. This morning it took about 15 minutes of effort, and the kids have been occupied all morning without the TV on. That makes me happy.
I should be able to fold the track up and store it in the basement for the next time I need a shower. ;)
