It sounds good - if I could afford care while I worked I would try it. But it is very dependant on the goodwill of others. The having to do it yourself requirement could be worked round by having school in the evenings and fun stuff in the day - can the existing morning person stay another hour - i would assume they had another job or school. I don't know what you do or what you get paid but might it be easier to reorganise your hours or reduce them (or your partner's)
