If you feel like any time you're around small children they start to cry, you're not alone. Not only might this make you apprehensive around kids, but you might start to wonder if something is wrong with you; do they sense something you don't? After a while, you might stay away from small kids in general just to avoid another embarrassing scene where they burst out crying the second they see you.Now, science might know the reason why.As it turns out, kids can be pretty judgmental, and who can blame them? For the first few years of our lives, we're really only used to being around mom, dad, siblings, and some immediate family and friends – or some other combination that makes up our family unit. Most children are shy before they get accustomed to being around other kids or strangers and those most familiar to us represent safety, protection, and even survival in terms of food, drink, shelter, and love.When it comes to trusting others, children simplify the interaction down to one specific trait that will determine how they feel about you: your face.
