On the days that my daughter, and not the childminder, takes my granddaughter to school, they go past my office, and I am required to give her a wave as she goes past. So I "see" het two or three times a week.
Depending on my daughter's work shifts, I either collect granddaughter from school or from the childminder two or three times a week, and keep her either at our house or at their flat until my daughter has finished work.
Before my daughter started working in April this year, we saw them one day every weekend, and usually one evening in the week for dinner.
