I mentioned to my DC that I was thinking about retiring, just exploring options, nothing even decided yet. Their immediate response was along the lines of “oh that would be perfect, you could help with childcare, school pickups, when they are ill, that sort of thing.”
I actually do not want to give up work and slide into being on-call childcare. I like working. I like having my own routine, my own space and my own independence. The idea that any flexibility automatically gets translated into availability for childcare does not appeal to me whatsoever.
I have friends who do regular childcare for their grandchildren and honestly they are constantly picking up bugs, dealing with sickness, plans being cancelled last minute because a child is ill. It looks absolutely exhausting. It is not how they imagined retirement but they got railroaded into it by their daughters/DILs.
I would rather keep working than be doing childcare.
