It's of course your choice, but just saying that that choice could end up biting you or the kid in the end.
No it's not fun hanging around kids all the time, but it takes a lot of not fun moments to get to the good parts.
This doesn't jibe with my experience at all. My wife is quite enjoying being at home with the baby, and gets to spend as much time outdoors as she cares for, even in the harsh Canadian winter.
Sure there are some sleepless nights (for both of us), but I'm not sure where this idea comes from that caring for a baby is a 24/7 slog. Close friends of ours had 3 children in 4.5 years, and even they don't talk like it's utter drudgery. I guess YMMV.
But that isn't true for all mothers. If a mother needs to socialize with other adults, or wants to chill with a drink with her friends, or go to a book club, etc. having a child that she must be solely responsible for 24/7 can be extremely mentally unhealthy. Maybe try Mother of all Podcasts? It's about comedian mothers talking about motherhood and being a comedian.
I’ve had enough adversity for one lifetime, my soul is weary, and refuse to submit to any additional unnecessary suffering. Without knowing my life, you’re not qualified to comment on it. I’m simply sharing my perspective having had my own kids and paternity leave offered.
