I think a lot has to do with what kinds of things you as the teacher likes to do - if you love to cuddle the kids, and care for basic needs then you are best suited to the infant room working one on one with each child. If you thrive on creating fun learning centre experiences and trying out creative art then you need to work with older children that can appreciate those same experiences. What I like about the toddlers is that they are at a crossroads developmentally and what I do for them and with them can totally change who they become in the future. They are filled with wonder about things we take for granted.
