Strollers ate not allowed to block aisles. I'm not sure you would want to bring in a stroller. The theater is older, and would make seating difficult.
I would say it would be very difficult to take a stroller I not the balboa theater. Parking is close by in Horton plaza, so leave the stroller in the car and walk in. Also personally I would only take a child of this age to a child friendly performance as the seating is narrow and it may be difficult if you need to get up during the performance.
It might be stroller friendly but idk about taking a baby to a theatre
There's a place where you can leave the stroller up front but you can't take it with you to your seat.
You shouldn't have any problem access wise but I'm not sure what the theater policy would be as far as walkway clearance. Perhaps give them a call.
