@muxvil, thanks that really helpful.

If you're formula feeding I suggest you have the water in the bottles already and formula measured out and in container. Put the bottles and formula in a big zip lock bag in your diaper bag so it's easy to take out at security line. They will check it.

You can check in your car seat and stroller for free.

Tablet with his favorite cartoons for entertainment and his favorite toy.

When you guys take off and land offer your baby the bottle so his ears won't pop.

Have him in his onsie so he can be comfortable.
