Opinions please. I'm about to start a new job teaching 3 days a week. My dcs are 14 and 11 and I've always used a nanny after school up to now. But is it time to let them 'go it alone' until myself or my dh get home? My main concern is they are at different schools and come home on the bus at different times. So my youngest ds (11) would have to let himself in at 3.40pm with my dd(14) getting back at 4.15pm on 2 nights and 6pm on the other. So my ds could potentially be home alone for almost 3 hours. My dh and I get home at differing times depending on where he is for work and if I have staff meetings, extra planning, parents evenings etc. Some nights we could be home at 5 and others it could be 7pm or later. I could batch cook lasagne etc so they could feed themselves or they could cook pizzas, pastas etc. what would you do?
