Milk for baby on plane?

[Alicia870]

This may be a stupid question but first time mum and first time on plane with baby.
She's just turned one and now has ditched formula and takes 3 bottles of cows milk per day.
The journey from where we live to airport is long and the plane journey is about 3 hours. Realistically we will be looking at at least 2 (and probably 3 given will want to give her bottle on takeoff) bottles during the time we're travelling.
But how do I do this? How do you keep the milk fresh? Do you just pack 3 bottles full of milk and can I just take them all through security? So confused!

You just take what you need for the journey to the airport, then when you have gone through security you can buy milk in one of the shops, or restaurants which is fine to take on the plane. You can use an insulated baby bottle bag to keep the milk cool.
