I've been a nurse in a pediatric office for about 15 years and I absolutely love it. It is important to have a lot patience and understanding with all ages. Try not to take anything personally. Triple check (at least) every vaccine before giving it. The most common vaccine error is with Tdap and DTaP, but there are others. Try not to get overwhelmed, there may be a lot to learn. Kids love bubbles. If the office allows it, blowing bubbles is especially helpful (usually) for 1-3 year olds, after getting shots or if uncooperative. Kids are awesome. Make it seem like being at the doctors office is fun! Good luck!
