My DS2 has 'significant speech delay'. He was assessed with this by a SALT & is about to start a block of 5 sessions with her on Monday.
The SALT feels that his delay is mainly down to his character, because he has been slow to meet pretty much every developmental milestone.
He has also been late with pointing. He has been gesturing to ask for things with outstretched hand for about 5/6 months now, which SALT said was good communication. He also around then started to point at things in books (more to touch the picture he liked than to identify it). In the last 3 months he has started using a finger to point, again mainly requesting things. Now, within the last month, he has started to point at things of interest with his index finger (then looking at me to see I've noticed, and saying 'ah-ah').
I feel this latter is a positive development for his speech, not least because I can label whatever he is looking at: 'Yes, DS, duck. Big duck.' etc. But I wondered if there is any correlation between when DC start pointing in this way & when they start talking? Am kind of hoping it means speech is imminent!
