My two cents,

If you are traveling with your husbend why not check to see if you and the baby can get bukkhead with baby bassoneit, and let you husbend sit with the other kid with an empty seat between (and hope the seat will stay empty or call the airline and ask if they can block the empty seat). Some airlines will do this if not ask if there is an empty riw during check in for hubby and the other kid to set in.

If the airline does not have bassionet then stick with the row and dont take tge bulkhead seat. It is easier to control you kids when the have row of seats in front of them and in back of them and you seating on the isle seat controling they escape route. The last thing you want to dose of and wake up to find your kid is not in thier seat. Bulkhead seats which are open will allow for a kid to leave thier seat while you are asleep.

Had this happen but thankfully my kid went to the restroom.
