My son has been seeing a chiro weekly since he was 3 weeks old. He has never minded, but make sure you choose a chiro who does family care - not all of them do. It shouldn't hurt them.
Drs said he had reflux at a few months old, but I refused to put a baby that young on meds, so I stepped up the chiro care, nursed and kept him upright for a little while after, and elevated the head end of his mattress. No reflux issues w/in a matter of weeks.
The meds scare me bc they are NOT tested and approved for children. Even meds routinely prescribed for infants have not been tested/approved for kids under two years of age. I don't believe in putting those things into their new little systems! We don't know all the long-term effects, so I'd try to manage as naturally as you can at first.
