Does the td/ipv hurt ?

A little: Are you referring to the combination dtap-ipv-hib that are usually given to infants at 2, 4, and 6 months? All shots cause a little pain with the needle stick, and sometimes you feel a little more when the vaccine is injected. I use a distraction technique that reduces the sensation of pain with shots. Most infants still cry, but I have had a few who did not cry at all!
