Yes, just because the OP was an adult traveling with two children. From aa.com:
"If you’re unable to choose seats, don’t want to pay for seats,
or chose a Basic Economy fare, our system will detect that you’re a family traveling. The system will search for seats together automatically before the day of departure. We’ll try our best to keep you together, but if seats are limited, we’ll assign seats so children under 15 are next to at least 1 adult."
