Have you personally known a woman that is an airline pilot and also a new mom? How did they juggle that if their partner is also a 121 pilot? Is it likely the mom will have to quit her career?
This article has a couple examples of mothers who not only were 121 pilots, but their daughters eventually joined them on the flight deck.
A pair of mother-daughter pilot teams, one at FedEx and the other at United Airlines, is making history.

The modern economic reality is that most families have to have both parents work. Pilots, or any other profession.
I'm just another corporate drone, as are most of my social circle. I've seen multiple different approaches to making it work. Sometimes grandparents step up and do most of the child raising. Other times, it's a lot of time in daycares. Or one parent "pulls back" in their career, still working full time, but in a less demanding role, so they can devote more time to being a caregiver.
Sometimes it works, sometimes it doesn't. For a pilot, or a family where both are pilots, I imagine a lot would depend on seniority. Good seniority means good schedule flexibility. Good schedule flexibility means a lot more options.
I assume location would matter a lot too. Lots more flexibility if you're close to your assigned base, as opposed to commuting in.
One anecdote I heard was a 737 FO (believe it was United) who had enough seniority to always fly the same route every day, with a schedule as such that he could drop his kid off at school, go to the airport, fly his line, and be home in time to pick up his kid. Obviously, he must have lived very close to his base, and had backups in place in the case of delays, etc. Also, that's like a 3rd hand story, so I'd be interested if any current 121 pilots could chime in on how feasible that was.
