We just flew 4 times. Families get to board after group A on southwest. Early enough for us. Yes, breast pumps, and milk are allowed on the plane. But I would print up the rules and bring them with. all 4 times we went though security they had differant standerds for our babies milk and food.
I just flew with a breast pump. At one airport they took the bag to the side, took out all the parts, and wiped them down looking for explosives residue But that was the only weirdness.
At home amongst the redwoods with my husband and my son, born 7/5/11, and #2 due in October 2015 Instant CNM, just add !
