When the Nursery suggested that he is behind on everything, have they suggested anything?
If the HV is responding to you, can you find out who their Boss is? You might be able to google it or your Doctor’s Receptionist may be able to tell you.
Alternatively, is there a HV clinic that you could get to?
I think you’ve already been let down by the HV. If he was behind at his 1 year check she should have followed up with you.
As well as the referrals to SaLT, a hearing test and to a Paediatrician to see why he’s behind I would also ask for a referral to Portage. As he’s falling regularly and over over DC at Nursery, I would also ask for a sight test and an appointment with Physio to check his core strength and if there is a physical reason for his lack of co-ordination.
I would also fill in both of these before you see the GP:
28 month Ages & Stages
and the 24 month Social & Emotional Ages & Stages.
On the first one, scoring in the grey in a couple of areas is perfectly normal as that hiw the assessment is designed, it’s not designed so that most will get all while.
On the second one, if he scores between 50 and 65 you’ll need a follow up appointment in a couple of months to monitor him. If he scores over 65 he should have an automatic referral to Paediatrics.
Unfortunately the services are so over stretched that it really is a case of those who push get seen so ring your HV every day, see if you can speak to the local HV team lead and insist on being seen and then when you are seen, insist on those referrals
