DS1 is nearly 3 now BUT until about a month or so ago he has been really slow with talking.

Last April we were assessed at a developmenetal clinic because he was not walking or talking, he started walking a week or so before appt at 21 months, with his speech they put us on a wait list which they finally called us 1 year later for appt and we have so far had 1 appt as other been cancelled due to sickeness.
I also did get a helath care plan from GP and see a private speech for 5 subsidised sessions. Which helped give me ways to encourage more words.

He has suddenly come on in leaps and bounds with many many more words and is putting words together now.

Good luck
