Deborah - you could hardly have a better outcome - boss already where you wanted to be and the team all excited. It'll be interesting to see how you head with the job share thoughts because it seems to me that you'll be doing days work in less than 5 full days. Glad that you have realized it was an answer to prayer
I have full confidence that if you do go down the job share path that you'd make it work for the person after your own experience.
BTW, has someone taken over your community meal program?
[and I'm sorry to bring up myself on your thread earlier, but in answer to your question, DH does all the school drop offs (DD12 takes the bus) and 2 pick ups. I do one, my MIL does one and my SIL does one. Takes an extended family to raise our family for sure. DH cooks 3-4 nights a week, including the nights we have people over. His work does have more flexibility, but he is putting in FT hours.]
