Bad parenting of Number 2

A bit of fun.
How did you manage parenting your second child's resentment dislike of their position in the family? Of course it all depends on their temperament, but here's one of my funnies.
DD was cross her big brother got on the plane ahead of her and sat in the window seat. Cue a big meltdown in front of 200 passengers. In the interests of a peaceful flight for all, my DH's answer was to offer to buy her 5 beanie babies at our destination. Job done! Except she then milked that one every time!
She was one who could easily be bribed.
