Call AF and request the kids business meal. It’s automatic when you book via AF, but all kids booked via DL come through to AF as adults. Our 3 and 5 year olds love the business kids meal. It’s chicken nuggets, veggies, pasta, apple sauce, a good dessert, some fruit, etc. It’s a specific business class kids meal. Way better than the coach kids meal and it’s even served on real plates.

I’d still suggest bringing backup food in case they get the catering wrong or you get rebooked due to cancellation or delay. We had this recently where the meal request did not carryover to the rebooked flight on the following day.

Safe travels!
