Theoretically possible, but even if she feels that way at age 20 it's not likely to be the reality at 35.

I know countless women who have dropped out of aviation (and the Navy) because of the child thing. The latest are two O-5 (sel) in my shop...one of whom is screened for command at sea but is going to retire at the end of her shore tour instead to remain in position for her kids.

I recommend soul searching for anyone entering this career, but women should maybe consider the child issue even more carefully.
