Dh has won an award (he’s a scientist) and there is a ceremony in Arizona to present the awards. It is a big deal and I’m very happy for him but it is a week long trip away from ds who will be 15 months by then. I have never left him even overnight before but dh isn’t really bothered and thinks ds will have a great time with my sister - yes I do trust her to look after him but a week seems like a long time to be away?
