Your questions for me on the closed thread could no longer be answered there so here goes. A pilot who is hardworking flying max hours could make as much as $50,000 as a CFI but that's assuming you can fly most days of the year. (and you are limited by regulation to no more than 8 hours of flight instruction in a 24 hour period.) There are parts of the year that due to icing aloft, or winds, no one is training in a small plane. When I was teaching out of Portland Ore, which got its share of weather, I made less than my friends working as McDonald's overall for the year and had to have a second job.
There are no rules regarding flying as a pilot while pregnant, but I had to stop at 7 months because I just got too big to pull the "stick" (the yoke) all the way back for a full-stall landing. It's not an easy career with pregnancy or children - morning sickness can ground you, and most doctors recommend you quit flying well before your due date. After birth breastfeeding is an issue -Pilots are
exempt from a provision in the Affordable Care Act requiring employers to accommodate new mothers.
I was pregnant at 18 and looking at a ton of student loan debt, no other job skills but flying and no one to help with the baby or help me provide for her (her father ran off and my Mom had just died) so I gave her up for adoption. If I'd been older and had other job skills that would have provided a decent home I'd have made another decision, but I had just turned 18 and was in college AND working two jobs.
Kelsey seems to me to be pretty level headed to manage a demanding career and motherhood.
