We have been to an osteo 3 times for Hamish due to his persistant ear problems. She checked him pretty well and said there was a little cranial rotation, but nothing that should cause all his problems.
Unfortunately I think they really wont do anything for a non-sleeping bub unless there is something majorly out.
We are in Geelong, and I dont rate this osteo that much to refer you to her. She's good, but not amazing. And my osteo doesn't do babies!
