Kate's delivery date is fast approaching. That means the royal couple's first child, George, is about to be (pardon the pun) dethroned. Not from his succession to the actual throne, of course, but Georgie will no longer be the centre of the universe to Kate and William. A new baby is about to be added to the Windsor family constellation and the entire family system will feel the shift.

First-born children become accustom to the constant attention and devotion of their parents. They are very responsive to their parents' smiles and approval, so first-born children tend to be pleasing and well-behaved little tykes. Their motto is: be first and be the best.

Enter baby number two! What will they be like? Well, they need to find their place in the family and they certainly don't want to be like their sibling.

Every child needs to find his or her own unique place in the family. It must be a different role than their sibling. To their parents, it will seem they have birthed the "anti-number one" child. "How could they be so different?" parents wonder. "We parented them the same, but they are night and day." If the eldest is a good sleeper, number two will be up all night. If the eldest is a good eater, number two is bound to be the picky eater.

Second children tend to look up to their older sibling and they will try very hard to keep up with them so they can play, too. It's a bit like the old "We try harder" adage from the car rental company Avis, which was number two to Hertz (this is often the motto of the second born).

Second born children are usually bigger risk takers, less concerned with perfection and mistake making. They have an ambitious "go-for-it" attitude. They tend to be more social and extroverted, an area eldest kids often struggle with.

If the oldest sibling is excellent at being "the good child," the second child takes the position of being good at being "the bad child." If this is the case, you will see more naughtiness and challenges to authority than you had with your first.

Is George going to have a baby brother or sister? We don't know, but this theory holds regardless of male or female. Gender does play a role, however. It's easier to feel more unique and less compared when you and your siblings are different sexes. The less alike the siblings are, the less comparable, the less they compete, the less they need to be extremely different.

Let's watch and see if my birth order and personality trait predictions come true for the Royals. Can you see how this plays out in your own family?
