Re: I think I might pass out
Best solution to flying alone with a baby = Make friends with flight attendants.
I'd bring something like a box of chocolate for the purser and the crew. It has to be store-bought and sealed. I might even include a note saying that you are flying with a baby on your own and while you are hoping for a smooth, non-eventful flight, you'd appreciate any extra help that could be extended to you and your baby.
It might or might not make a difference but it's worth a try.
