Good afternoon --

I'll be flying ATL-HNL in about two weeks with my 2 year old and a 2 month old. What are some folks experiences with baby food and milk...i plan on buying milk at an airport shop past security to bring onboard as I don't remember seeing it as an option during service. We'll have plenty of activities, snacks, baby food, etc., for the kids. My only concern is keeping the milk cold for them. Any thoughts on what a best practice is?

Best,
Plink
