We're planning on taking a short (1-2 hour) air trip in a couple of months. Our son will be 11 months old by then.

Given the delays with getting through security, the amount of time in advance we'll need to arrive at the gate, and the duration of the flight, we're assuming we'll need to feed him at least once during the trip.

However, with the restrictions of airport security, we're not sure if we'll be able to bring food with us.

Can we bring bottled breast milk? Powdered formula with water? Jars of baby food? All of those would need to exceed the fluid volume restrictions in place for carry-on baggage within the US. Are exceptions made for infants? Would glass jars for the baby food be an issue?
