2. You get new toys, clothes etc.
3. You get more privileges and get to do things first. It's wonderful watching your younger sibling/s stomp off sulkily to bed, while you get a later bedtime.

5. Usually you're physically bigger than your siblings for at least the beginning. All the better for letting them know who's boss.
