1. They believe in Santa.

We all can remember the age where we still thought Santa Claus was real. It is part of everyone's childhood that is a special memory to them. The idea that children think that a man flies around the world and delivers presents to children, free of cost, every December 24 shows just how innocent children really are. If only the real world could be what they dreamed of. Let's also not forget that children think that a fairy will give them money just for losing a tooth, or that a rabbit will hide Easter eggs around their house. It seems insane to us, but to little kids, it is a part of their world.

2. They are freaked out by children of the opposite sex.

This still exists to some extent, but it is amazing to think that little kids genuinely have negative associations with the opposite sex, up until a certain age. It is crazy how girls in elementary school refuse to be partners with a boy, or think they have some type of germs. It is remarkable how the human brain can evolve as one gets older, so much that you can think of another person in a completely different way than before. As adults, most people do not genuinely fear the opposite sex, and definitely don't think they have cooties.

3. They can be entertained by the simplest of things.

Babysitting can be one of the easiest and hardest of jobs, because while young kids get bored very easily, they also can be entertained very easily. You can give basically anything that you have in your possession to a little kid and there is a good chance they will be fascinated by it, if you give them a reason to be. The best thing about little kids is they love the simple things in life.

4. They are the world's easiest television critics.

I've noticed through the years that some child television shows sometimes have characters that can even look a little creepy. However, little kids don't really see that. Take Sesame Street, for example. If the average adult were to see a show featuring a monster who lives in a trash can, they might question it and think it was a little strange. However, to little kids, a monster in a trash can is something new and fun that they can see and learn from. They really are just curious about the world around them.

5. The thing they look forward to most is coming home to their parents.

Every adult remembers how awful it would be when they had to say goodbye to their parents before they went to school in the morning, especially at the kindergarten and elementary school age. It was always traumatizing leaving your mom and knowing you wouldn't be able to see her until the end of the day. Everyone can also remember how upset they would be if their parents didn't tuck them in goodnight. Some of the worst night's sleep people got as children were the nights when they had to be put to bed by their babysitters, or had to spend a weekend at their cousin's house. As adults, most of us forget just how special our parents are to us. Little kids think of their parents as their world, which is how all of us should be, even when we are older.
