For children in our school nursery I refer to our Early Years SEN team. They monitor, liaise with the HV etc and then do put SALT referrals in. It may be different in different LAs but I often refer nursery age children who are nonverbal and the majority get a communication plan etc in place. I think what I was trying to get across was that there is more that she can do than put an insta post out.With the greatest respect, a nursery or HV referral to SALT will be for a child who has difficulty with pronunciation or some simple speech delays. A non verbal child won't be referred direct to SALT or if they are will be be referred on to multi disciplinary team.
Without a diagnosis, no amount of money changes things.
