My child had her first Chiropractic appointment at 6 months and many babies are adjusted much earlier as well! She had some small adjustments during my visits when she was just 2 weeks old! I have also heard stories of colicky babies going to a Chiropractor. Shortly after, the baby's symptoms were almost gone! It's worth a look.
