Acupuncture needles are solid and much smaller than the hollow needles used for injections or for drawing blood. Some patients feel only a small pinch as some needles are inserted. Many feel no pain at all.
We knew something was "not quite right" from the time my son was only a few days old. He didn't like to be swaddled, and he screamed when placed in the confines of his cradle, bouncy chair or car seat. It broke my heart when night after night my newborn baby refused to be comforted in my arms. Multiple visits to his pediatrician simply labeled him as a "fussy" baby and me and my husband as "paranoid" parents.
We finally got his doctor's attention when he started missing verbal milestones. He didn't coo. He didn't babble. And finally, months after a time when speech should have come, he didn't talk. Not one word.
