In your case, I think the FA should have been more considerate. Albeit your child was acting up, but lots of FA's accept that. In addition, as well all know, the airlines know all to well that HI routes are ones often used for vacationers/families. If they are going to scale back their service because of the large amount of leisure travel, they should atleast ackknowledge the increased volume of familes and adjust their attitudes accordingly. All in all, the FA acted without compassion, I am assuming that no one in the cabin complained, so why ruin your flight.
