1 day every week free childcare. 1 day every week cleaning. 1 day every week emptying the bins. 1 day every week picking up the dog's poo. 1 day every week sorting out the washing. 1 day every week unloading the dish washer. 1 day every week getting milk & any other bits. Yours, a tired grandparent😩
What do you do the other 6 days that makes you so tired?
I have a disabled brother and an elderly mother to care for as well. Yes and strangely enough, somedays I sit on my arse and do something for myself.
Sounds like you do a huge amount of mucking in and that the OP want aiming their comment at you, or grandparents like you :)
