Ds has just turned 4. it took around 18 mths mostly due to the mis communication of the process of getting diagnosed.
We seen a GP 1st who referred us to a child pyscologist as we live in the NT there wasnt one available for a while so we had to wait, when one became available we had an extensive meeting with them and then back to the Gp we went who then referred us to the pediatrician. we seen him several times before the diagnosis was given.
hope this helps
