My oldest is very responsible, and if it were just her, I'd trust her home alone. But my middle child (9) is not responsible at all, so there's no way I would leave him home alone at this point. And I don't want to have my oldest in charge of the other two yet.
The salesperson for the new development we are buying in emailed me a name of someone who does childcare today, so I am getting some leads there.
I am soure it will all work out. I am such a Type A planner though that I overtink things. I should just sit back, wait for the interview and job offer, and then just see what happens.
