I did SEA-ORD with a 3 year old who keeps to herself. Parent of a another kid wanted my kid to play with her kid in the bulkhead of E+. granted it would have affected her legroom. I declined. So she offered the aisle so I could watch my kid if that was what I was afraid of. I declined again. Ten min later her kid is running screaming up and down the aisles after a passenger dumped water on the kid by accident after we hit turbulence. My kid was contently watching The Lion King on my iPad with headphones on. Yet again I'm also one of those parents who keeps my kid occupied on a flight and out of the way of fellow passengers. Heck. I've even bought passengers a drink if my kid unconvinced them in any way. Last flight kid kept kicking the seat in front of her for like 5 minutes. I bought the guy a drink since he was obviously annoyed.
