Baby food / formula
My wife and I will shortly be taking a rather long flight from Heathrow to Auckland with our twin babies.
My wife will obviously be doing her best to produce the stuff herself but with twins you normally need to top this up so I've been trying to find whether the liquid rule is flexed for baby formula as we could need rather a lot to get them through a 24+ hour long flight.
I know that they will let you through if you have a sip yourself but what about unopened cartons? Formula only stays fresh for a few hours once opened unless it is refrigerated so opening the packs and taking a sip isn't really do-able.
Alternatively does anyone know if you can buy the stuff on the other side of security?
