What a bunch of stupid garbage. Do you know how much space there is between the bones of a newborn? It would be nearly impossible to tell if anything is out of place.
Chiropractors can be complete con artists. There's one here that will lure you with free tickets, a chance to win a truck, and all sorts of free massages afterwards and god knows what else. Then they'll have you x-rayed in a bad position then tell you from that you have horrible spine issues and then you've got to pay them hundreds per month to fix it when it really doesn't fix anything.
