No. Just don't go. You chose to raise a child, part of that includes not dragging them where they don't belong until they are old grown enough to behave. If you have to go, arrange care for the child while you are gone if they aren't mature enough yet. Bringing a baby on a plane says, "I refuse to pay money to take responsibility for my choosing to have a child, so I'll bring it with me and put that burden on everyone trapped with me on a plane." Gee thanks.
