So we just booked a trip to fly to San Diego from Minneapolis with three adults and my daughter who will be just under 12 months at the time.  The flight is 3 hours and 45 minutes.  I’m very nervous about flying with her as I don’t want her crying the whole trip and disturbing everyone on the flight… Any advice as to what to take, what to know what to plan for?  My husband has already asked the question about what we do if we need to change her diaper… but any advice I would greatly appreciate!
