I am retired, and quilt whenever I can. Some weeks I get a lot done, others I hurt to much to quilt so I read/watch videos/surf the internet for new techniques and tips :D:D:D
When my kids were still at home, I did take time in the evenings for myself, even if it was only a half hour.
I think it was good for them to learn and know that their playtime was good and healthy for them, mama's playtime was good and healthy for her too! As they got older I could get an 1 to 1 1/2hours some nights, but we ALL shared the daily chores, and none of us spent more than 30 minutes each (excluding laundry) each afternoon/evening :D:D:D
