I offered to do a day a week when my DGS1 was born. It was my choice and suited me and my DD1. I was still working f/t but could jiggle hours/work from home etc. so it worked!
I now look after bot sets of DGC 2x week after school. But if we wan to go away we just give advance notice and the DDs sort it! They are grateful for the support we provide and do not begrudge us if we plan a holiday! You have to do what suits you and your circumstances and be absolutely clear in communicating !
Have any of you got all electric cars? Pros and cons please.
