Overnight flight... Tips and advice, please!

Alicia

We're moving abroad in a couple months and will be taking our 3.5-year-old and 15-month-old on their first flight, which will likely be overnight transatlantic... with two cats and a crap ton of luggage.

While I know we'll survive, I'm really nervous and would greatly appreciate any tips or advice you guys might have!

Thanks so much!!!
