If they see something they want, they'll do whatever it takes to get it. They'll scream, sure, but they'll also hit their head, injuring themselves, so their parents feel bad. One bumped head and suddenly every cookie and toy goes to the baby, and Mommy is cooing, "Are you alright?"
This behavior of self harm and manipulation usually starts before six months and can continue well into childhood. During tantrums, babies will hit and bite themselves, and some children will hold their breath for so long they pass out. This emotional manipulation is, not surprisingly, very effective.
Why Did I Do That?!
Children don't have a complex understanding of other people's ownership until they are a few years old. Unfortunately, an understanding of personal ownership comes much sooner than that. In other words, to a baby, everything is theirs. The concept of things being taken away makes no sense. If it's MINE and I want it NOW why can't I have it? Since everything is rightly yours there is nothing wrong with doing whatever you have to do to get it back. And if it takes making yourself pass out to get your damn pacifier returned, so be it. What do you care? You're a little con baby.
For a long time scientists had a theory that left handed people might have started out as twins in the womb. Their rationale was that in a set of twins one tends to be right handed and one left handed. Genetic and nurturing factors can also affect handedness, but they can't explain it completely in many cases. Maybe all lefties were the result of only one twin surviving the cage fight that is fetal development.
It wasn't until ultrasounds, and fearless cameras capable of surviving the uterus, that scientists discovered their hunch was right. Sort of. They were right in the fact that most lefties were once twins but they didn't go far enough. Scientists now think that a ridiculous one in eight people started out as two peas in a pod. Of course, only about one in 70 people actually is a twin. So what happened to your twin? You killed it and then absorbed it into your body. Yeah, those stories of adults finding teeth in their shoulder? Not urban legends.
Why Did I Do That?!
Because you're evil.
Not really. Chances are you were just the healthier fetus. Or you hogged all the blood if you shared a placenta. Or you grew faster and literally left your sibling no womb at the inn. If multiple pregnancies are really as common as they now seem, we evolved to be this way for a reason. Trying out two fetuses to see which one is more likely to survive is a pretty good plan evolutionarily. Unfortunately, carrying twins is very dangerous for the mother, meaning that our best bet as a species was to let one twin kill off the other early on in development. Just another reason lefties are a sinister, sinister group of people.
