Baby sleep, please

CUrrently up, extremely tired, it is 3:30am. With a crying 10 month old who's been up for over an hour. Fed. Changed. Fed again. Rocked. But he wants to play. So he's been screamcrying for half an hour because he doesn't want yo sleep. But we have to be up in 2 hours because we have a flight to catch 🙃 how the fuck am i suppose to handle flying alone with two kids (a 2 year old and this screamer ) on literally no sleep. The flight is 3 hrs long. Not too long but that doesn't include the being in the airport time. I don't get why this bsby won't sleep, i want to cry
