8.) Tracking devices: The Giggle Bug toddler tracker works similarly to those fobs that help you find your car keys. Except this one's louder. And you clip it onto your kid.
9.) A great stroller (or two): The Sit 'n Stand LX is a stroller with a toddler-friendly jump seat. It's not much bigger than a regular stroller -- definitely a plus in a crowded airport. Not to be confused with the Sit 'n' Stroll, a combination carseat-stroller-booster seat we use so often that I'm dreading the day our youngest outgrows it. Also, Quinny Buzz pushchairs have ground breaking gas spring technology allowing you to unfold the chair with just one hand.
10.) Quick diaper changes: The Pronto mini-changer
by Skip Hop keeps everything you need for a diaper change in a compact, easy-to-grab clutch. Don't feel like investing in yet another bag? Keep an extra diaper or two and slim package of disposable wipes in a plastic grocery bag, roll it up, and stash it at the top of your carryon instead.
