We are traveling to Hawaii which is a 12 hour flight for us. I will pack a skip hop backpack for my 2 year old with her toys a couple of her snacks and (empty) water bottle.

I am a notorious over packer but I don't want to be schlepping an over packed bag. I can load my husband with some stuff but the bag he prefers to carry isn't huge. We have a two hour layover to think about as well. Any tips for keeping it to a minimum?
