Flying with infant.

Hey ladies! So I'm flying from Colorado to San Antonio, Texas this Thursday with my 7 month old to see my little brother graduate from Airforce BMT. There is one layover. I have never done this before and a little nervous about it.

Any moms with experience have some tips for me? I read that feeding them while taking off and landing would help with their ears, is this true? She's at the age where she wants to be moving all the time and get mad when I don't allow her. So yeah, help me lol
