I didn't get my son a seat as luckily (totally by chance) I always had an empty seat next to me. When I travel with my son it's always just he and I so since its you and your wife you should be able to manage probably a little bit better than I did. My son was 17 months the last time he was in Jamaica. I can say his eating habits totally changed while we were there since he was out of his element. I went from a kid that would eat anything I put in front of him to the world's pickiest eater. Oatmeal, rice, some chicken, grapes, and fries were about all he ate while we were there. No matter what I tried to give him, he wouldn't eat. He is almost 5 this next trip and right now again, he is eating just about whatever I give him. I hope that doesn't change. I have oatmeal, frozen grapes and yogurt just in case LOL
