I took DS2 from early on (4mths approx) to my Chiro (on Milne rd Modbury heights area) and I would say its been good - less sleep issues than DS1 who I only took from about 3yrs old. My Chiro is doing training to work with children as well as adults; also has a good rapport with both boys. We currently go 3 monthly with the boys but if something's not right we can easily get an appointment earlier; originally I think we went weekly for about 3 weeks to make sure everything stayed right.
