Just wondering since we booked our tickets today. My son will be 11 months old and we got him his own seat since it's 8hrs of travel time & he's very big / heavy already.

Will he have any concept of Christmas whatsoever? Opening presents, those are gifts for him, etc?

We are thinking of having a "birthday" party for him then too because my parents won't be able to be there for his "real" birthday.

I don't know, I'm just wondering what it will be like.
