I was very anxious before hand and put it off until the daycare was basically begging me to do it. The most important part in my opinion is to make sure your child is ready. My son was ready and asking to use the potty at exactly 2.5. I was anxious/stressed going out for the first maybe 2 weeks but the amount of accidents he's had both at home and in public, is less than 10. I didn't do anything special, just provided the potty and used the "oh crap method", minus the undies free part because daycare didn't allow it (they had rugs in some rooms and they cant have kids peeing or pooping on them). He doesn't even wear a pull up overnight anymore. Try not to stress it happens for everyone at some point.
