Hi there, I traveled with my three boys when they were one. The whole trip was about 3hours, and I really thought everything through and packed everything we needed, or what I thought we needed. The boys were still having bottles, so I packed one bottle each thinking it will be enough as it was a relatively short trip and they were fed before we got on the plane. But that one bottle was gone before we even left the ground. They cried and cried, so my advice is pack a few bottles, it will sooth them while the plane is taking off or during landing. Don't put shoes on them, just socks, it was a hassle taking shoes off and having to put them all back on and we just didn't have enough hands. Pack a big bag with everything, I packed three little bags and it was time consuming getting things out of three bags. We hired a vehicle with three carseats, it was so much easier than taking our own. We did take our twin and single stroller, but they had to be checked in and after we landed, we had to walk the three boys to the baggage collection and it took a very long time, and my arms were killing me, I was only carrying one boy while DH was carrying two lol.

Good luck on your trip. If they cry, they cry, it can't be helped.
