Rivka. You CAN homeschool your kids- it may not be easy, but it's definitely do-able. It's a shame we don't live closer- you could come visit and let my girls take care of the twins for a few hours (they LOVE playing with babies and little kids!) while we could sit and chat.
As far as getting playdough out of the carpet- just do the best you can. If it's wedged in there so tightly that you can't get the last remnents out, then those remnants aren't going to come loose during Pesach either. They'll become "as ownerless as the dust of the earth" when you make that declaration after the search for chametz.
We're almost done with Pesach shopping- well the non-perishables anyway. I still need nuts, sugar, and a few more jars of gefilte fish, and packing tape to fasten the "shelf liner" to my counters. I haven't even begun buying meat, dairy, or produce.
