Every daycare has its own unique balance of individuals. The kids all take their roles: leader, follower, quiet, attention whore, crier, etc. Where your child fits into the room dynamics says little about them in the long term and can change as other kids come and go from the population. But there are certainly niches that are more or less desirable as a parent. This is particularly true WRT the predator / prey relationships.
If you have ever gone to pick up your child and been confronted with the dreaded "incident sheet" you immediately think "Fuck, please let my kid be the one who got bitten." Whereas that may be counterintuitive, you have to bear in mind the alternative. If you have the class biter, you basically feel like you are raising this:
Our first child was the preferred prey of the class biter. As much as it sucked to pick up our daughter looking like she lost a battle with a lamprey, we were also sympathetic to the parents who had to sign the "yes, we realize our child is a bath salts incident away from being Florida Man" sheet. You can't reason with a toddler and explain why it's bad to cannibalize your friends. They don't get it. You can discipline them after an incident, but it takes time for them to change their behavior. As a parent all you can do is wait and avoid eye contact with the other parents of kids in the room, because some get it and some think you spend your every waking moment teaching your child to devour the competition.
This is all relevant this week as the tables have turned and we were faced with signing our first incident sheet from the predator's side. It sucks as much as we imagined.
