DEAR DOCTOR K: My daughter’s pediatrician would like her to have the HPV vaccine. I’m not sure. Is there evidence the HPV vaccine has some real benefit? DEAR READER: Yes, there is evidence — overwhelming evidence. And with this vaccine, the benefit is not that it will reduce the risk of a short-lived illness, like the flu. This vaccine will reduce your daughter’s risk of getting a common and life-threatening cancer.

DEAR DOCTOR K: I have two young children. I know not to buy toys with small parts or keep coins within their reach. What other choking hazards should I be aware of?

DEAR DOCTOR K: I recently discovered that my teenage son is smoking. How can I help him quit?

DEAR DOCTOR K: I’ve started giving pureed solid foods to my 2-month-old daughter. My sister doesn’t think this is safe. What’s your opinion?
