Packing for sun
Since sunscreen isn't best for little babes, it can be hard to plan for extended time in the sun. We used a sunhat for Henry and then covered him with a thin swaddle blanket, which kept him pretty cool. I also wore a wide-brimmed sunhat and it kept him in the shade when he was in the carrier or in my arms.
Flying with an infant
In my opinion, it's so much easier than driving with an infant. You don't have to worry about the car seat, and kind people keep bringing you snacks and drinks. Because of the baby, you are also invited to go to the front of most lines in the airport. I was pleasantly surprised to find that fellow passengers were very warm and welcoming, not annoyed to be sitting next to a baby. Here's what we'd recommend.
• Check the car seat Most airlines will let you check the car seat for free, and it was nice not to have to pay to rent a car seat with our rental car. Also, it was reassuring to have a car seat that we knew fit and worked well for our baby. Most international cars use the LATCH system, just like in the States. You can purchase a large bag specifically made to pack a car seat on the plane. For us, the car seat bag was worth it. We also padded it with diapers and wipes and a foldable bassinet.
• Check the stroller at the gate A friend let us borrow a lightweight and compact travel stroller, and it was nice to have the stroller in the airport. We also used the stroller at the beach to keep him out of the sun and sand.
• Request a bassinet for the flight Most airlines offer a cute little bassinet for babies up to 20 pounds or so. Henry slept and also played in the bassinet. We were grateful to have somewhere to put him besides our laps.
• Feed the baby during takeoff and landing Henry didn't seem to have any trouble with his ears popping, maybe because we nursed on the way up and down. Many folks recommend it.
• Fly through Amsterdam airport We LOVE the Amsterdam airport. They have a gorgeous baby care lounge, a children's library, a children's science museum, and plenty of great places for kids to play. It's all free of charge.
