Does anyone have advice for long flights with a LO under 2? We are flying to Hawaii in 6 weeks and I can't decide if buying him his own seat is worth the extra money. He's very active and hates being held for long periods of time unless we're walking. I figure if he gets tired in his carseat, at least he could take a nap. But I'm wondering if anyone else has had any experience with this? Also does anyone know if Alaska airlines has enough space for a big carseat without him kicking someone in front? I'm really stressing about this and just want to make the right decision so we have a peaceful flight.
