Dave needs to get a bloody full time job and provide for his family, together with her part time one of course. Then perhaps they could get a mortgage on a home of their own instead of planning another baby in a rented house.
Here in Ireland, many renters are being evicted by landlords wanting to sell and it’s leaving families homeless. They cannot depend on that being their home forever and should be getting their ducks in a row. I’m sure they could then buy cheaper up in Scotland and each have jobs with Nana Fran and family to help with childcare - if Sophie would just get off her high horse about location!
