Obviously you havent observed and/or assisted on a pedo case. More power to you...but have fun!!!! Kids can be much worse than adults...they kick and scream and cry. Not to mention the small oral cavity that we will eventually work in becomes much smaller when working on children. I have to say touring the NYU pedo clinic last year when interviewing cured whatever thoughts I had about doing pedo.
For all those who want to specialize and havent even started school yet...how the hell do you know? Additionally, who says you wont change your mind in 4 years? Maybe you have shadowed and thought it was cool, but until you experience it I think its tough to say I want to specialize in X, Y, Z. Ask a lot of dental students and they will say "I just want to get through"...thats how I will view the next 4 years.
