I recently asked myself this exact question and had the opportunity to try it out. Last winter I had my first baby and stayed home for 4 months on maternity leave while my lesbian partner worked full time.

IT WAS HELL.
I love my daughter and I love spending time with her. And my partner helped a lot- way more than I would expect a man too. But honestly I have never been so tired and exhausted. Staying home full time with a child is extremely demanding. I’ve never had to work so hard. There were no breaks. No 15 minute breaks every 4 hours that I get at work: I was expected to work even while I was asleep.
My Lesbian partner make’s enough money for me to be a SAHM if I really wanted it.
No thank you.
Getting up and going to work for 10 hours a day is waaaaay easier.

I know some women love it, but for me it was the most exhausting, awful work I’ve ever done.
If I was alive in the 1950’s I honestly think I might have killed my self.
I went back to work 2 months ago and I am so much happier. I come home from a long day of work to spend 4-5 hours caring for my daughter in the evenings. My daughter loves her Nanny. She also loves me, but we aren’t forced in each others faces all day and our relationship is way better.
No, I’d rather work it’s way easier.
I’m a teacher, so I have the summer off. I’m currently scrambling to get a summer job just so I can work.
