Step 1) Infant tylenol about 10 minutes prior
Step 2) Realize that stubbing your toe hurts more, and your baby is not only going to be stubbing her toes, but her FACE, head, elbows, knees, bum... not to mention slicing her gums open for the very first time (teething). She's going to skin her knees and elbows, get stung by insects, burned by the sun, bend a nail all the way back to the quick. Give her a little time and you'll watch her first heart-break. (You won't have to wait that long btw, my son's first broken heart was at about a year and a half) She'll also catch colds, flues, & fevers that will last for DAYS worth of pain and misery, as opposed to a few seconds. Pain is all a part of life. We CAN'T avoid it, and live happy healthy productive lives. Although addicts certainly try. Life without pain is life without joy, love, & striving to succeed, to be better. Life without pain, isn't life. It's death.
Step 3) Which brings us to the fact that these are immunizations. Which keep her from contracting one of these deadly diseases that are on the rise. Would you trade 4 seconds of pain and an afternoon of sleepiness for your daughters life? You know you wouldn't. If you can endure however many hours of labor to bring her into this world, you can endure one indignant moment to KEEP her here in this world.
<Grinning> You'll be fine. She'll be fine. We all stress out over this stuff. Sometime we all just need a good icewater reality check. Not only will she undoubtedly have MUCH worse, but being squeezed out of a hole smaller then your head can't feel too fantastic, either... so quite frankly, she's probably already HAD worse.
