Aww poor Oliver! The pediatrician forced us to give Arthur some Nutramigen after every feeds during the first week (which was not the right thing to do in our situation but whatever). He hated it so much he would scream and scream until he'd throw up... then the last day it looked like he had gotten used to it. Hopefully it'll get better for you as well!
We had our first long car ride with Arthur this weekend and it went better than expected! On our way to our destination, Arthur fell asleep after only 15 minutes on the highway, woke up 2 hours later to silently look out the window, fell back asleep right away and finally woke up for a feed when we parked the car. The way back home went even better than that: he fell asleep as soon as we left the parking lot and only woke up when we got home, 3 hours later!
He didn't like sleeping in a strange bed though. He wasn't a big fan of the family reunion either... too many people he didn't know, too much noise, too many photographs taken when all he wanted was to be nursed. Seriously, I spent 15 minutes repeating that he was hungry, but they would not give him back to me and they were like, "why is he crying? make him smile so we can take more pictures" um, nope, not going to be able to do that unless you let me go and feed him. I'm glad my family loves Arthur, but that really annoyed me.
