it doesn’t have to be a kids meal, you could find something your child might like and order from chef on call
I have no personal experience to offer, but did you try calling the airline? From their site it seems you can make specific requests if your child is a fussy eater:
If you are travelling on a flight that has a meal service, our special Child’s Meal (CHML) is nutritionally designed for children aged 2 to 12. The exact meal served depends on the flight sector, so do call us in advance if you would like to make a request.
- This service must be requested through the Reservations/Ticket Counter/Call Centre at least 24 hours before departure. Please call 1 300 88 3000 if you are calling from within Malaysia or +603 7843 3000 if you are overseas.
Also try searching airlinemeals.net:
