Not the clearest of photos, but it's hard to take a photo in such tight spaces
Besides that though, we didn't have any issues with her. She nursed during take-off. (Of course while I sat next to a guy who looked to be in his late teens or early twenties. A little awkward, but we survived.) We brought her stuffed hippo, which we've napped trained her with, and used that to get her to take a nap in my arms. She ate some homemade hummus we brought along as a snack and drank some water from a sippie cup. She did nurse about an hour before landing which was a little awkward, but used her pacifier during landing and didn't seem to have any issues with the pressure change.
Our flight actually landed pretty early, intentional by us to make sure we could put her to bed at a normal time. But while we made it back to my dad's at a normal time, we spent the rest of the day hanging out at the house since even though she was good for the 4-hour flight, it wasn't what I'd list as relaxing.
