Help please

hi everyone, 

im new on here. I had a meeting with an early help assessment coordinator this week who told me he thinks my son is autistic. I do agree with him. I’m looking at getting a private assessment done. My only concern is that I forgot to mention to him that my son does talk sometimes using a made up language . Is this a trait? Also do children with autism develop turrets at all??? My son says ‘idiot mum , idiot mum’ and ‘poxy idiot’ . Is this early turrets (unsure of spelling sorry) . Any help us gladly appreciated xx
