This is a bit of a pet peeve of mine, so now you are forewarned. I think a little pre-school is great for the reasons Saritz mentioned. A little break for mom is never a bad thing! But in my neck of the woods, parents treat it like it is a necessity to "prepare kids for school." Phooey! That is a complete fiction, unless we are talking about kids from impoverished backgrounds. (And yes, I chose not to send mine to preschool which was a little lonely and hard for all of us, but I'm glad I did it now.) Check out this summary of the research of pre-school:
