This resonates. Especially since having a kid, the tension between solitary and family activities at the weekend has been a real struggle.
Back in the "old days", people lived with multiple generations under one roof and with their extended families. So raising kids was easier because you had a lot of help: grandparents, uncles/aunts, etc. Then the "nuclear family" came along in the 50s and things started falling apart. It was OK for a while because women were relegated to near-slavery, but then things changed and we had two working parents, and then there wasn't enough time to parent properly.
The first option that came was to reduce sleep to gain free time, definitely not a good idea on the long run.
