To ask for equal undisturbed hobby time at home

[Fitbitironic]

To keep it brief, dh's interests have him out of the house for a couple of hours at the weekend (effectively taking out a morning), and at least one evening every week. Sometimes additional times, and it can be for longer.
The rationalization has always been that he would look after DC if I wanted to do something, so I can't complain. The reality is that my interest is more home based, so I'm still regularly disturbed by DC, cutting into my time and breaking concentration. It's not something I can just pick up and take elsewhere. Also wouldn't be doing it all through the school day due to other commitments.
AIBU to tell him to entertain his DC (quietly) for the relevant length of time so that I have my undisturbed hobby time too?

Evenings, (after about 7pm), are the best for food shopping where I live. There’s nobody in them! Can you do that op? Leave the dcs with dh and get all your shopping done in one evening.

Yolo , my eldest dc is 19 and has certainty not be raised as a special snowflake.
She does know that I managed my time well enough to spend time with her and her siblings.

digging in the garden, mopping floors and scrubbing toilets etc is a darn sight more physical than sitting on your arse in front of a computer.

Yes, except a lot of people sit on their arse in front of a computer and then STILL have to do all of the above in the evenings and weekends. Your kids are in school, you can find time during the day.
