I have traveled long distances twice this year with my (now) 7 month old and (now) 4 year old boys. Here are the keys to success: travel light and pack what you can in your checked bags; if you are traveling with "medical liquids" (formula/breastmilk/etc.)as the TSA calls them, make sure they are in one place, are accessible and not at the bottom of your carry on when you go into security - trust me, planning ahead like that with little annoying things like getting stuff out of your luggage for security makes it easier; slip on shoes if possible, even for your kids - all shoes have to come off; bring snacks and things you can bribe your children with that they may not get at home (i.e. candy, cookies - special treats);bring little new small toys to keep them occupied to hand out before things get crazy - aquadoodle travel size was a hit with my 4 year old; peanut butter sandwiches travel nicely and fill tummies; DVD player with favorite movies (although we do OK without one); markers/pens and paper to color; favorite toy/blanket for napping (best case scenario is sleeping kids!) and **most importantly** --your patience. Because going to the airport and getting on a plane even when you are by yourself is stressful enough, it is critical that you leave yourself enough time to get to the airport, to take time parking, to get through security and to your gate a little bit early and not get frazzled or anxious - kids take their cues from you! I can't tell you how many times I have seen stressed out parents dragging their screaming kids through airports. Your trip will be so much better if you just find your "calm" and power through this - with preparation, you will have a more pleasant trip. I should add that I am sorry about your mom - good luck and safe travels.
