Easter is on the horizon. Tell them that is your cut off point. You are sorry but you are too tired and cannot do daily childcare. Decide what you will do - one day a week or two afternoons or perhaps nothing. Be firm.
I agree with above. I love and adore my GC but would feel like you Mrs.S if I had them 4days per week. I did agree to around 3 days per week before my first GD was born, but my DD decide to be a stay at home mum till both girls were in school, so I got away with it
. I do always say yes to any babysitting, full day, sleep-over etc; only fair.
