Firstly you know your boy - do not be fobed off.
I have 3 ds's (now 5.5yrs, just 4yrs and 2.5yrs) all 3 have had grommits this year.
ds3 was referred due to speech and language delay after 2yr check, at audiology clinic I was told he had glue ear but we should 'watch and wait' and it wasn't genetic - I walked out, ds1 suffered dramatically by them letting us wait, and they let us wait for 8 months through reception before we got to see an ENT consultant - how can you pick up phonics is you can distingush between sounds
School defiently failed to recognise the impact his hearing had on his behaviour and schooling - at still do
he has IEP and on School action plus - last year they wanted to refer him to CAHMS for ASD... this year 'that isn't necessary'
my parenting confidence is shot (but thats a whole other thread!)
Anyway for reference, you can be genetically predisposed to glue ear Research at John Radcliffe Oxford which we have been part of since ds1 had grommits in March so I knew audiologist was talking bullshit
and I think you need to know what to expect Nice guidelines the lovely Research Nurse sent me these after our expericence with ds1 hence I don't trust our local audiology clinic, we waited too long - I have to say our ENT Consultant is fab (only 5 week wait on NHS for grommit op for ds1) but we went private for ds2 (hearing test one week, grommits the following week), I wasn't sure about ds3 (with hindsight his speech is very similar to ds1) but after their comment we went private to consultant and couldn't have private op (due to his age) but got grommits done on 23rd Dec (6 week wait)
Since you have been referred to ENT already I think you'll be fine
that was the tricky bit for us, once we'd seen him the op date was quite quick
ds3's speech is already improving, its only been a week - and I can honestly say it has had a profound affect on the other 2, both speech, socially and behaviourally. This year has been a revelation for me - ds1 was in awe that leaves actually 'russel' he could hear them on walk home in autumn, he sat for an hour on the beach listening to the 'noisy sea roaring' in May and both him and ds2 are singing, its normal stuff I never realised they never heard properly before. I have so much more understanding of how hearing can affect people.
My dh had quite a few sets of grommits and grew out of glue ear at 7 so we might have to go back, at the moment I'm looking in to the Ovent nose balloon to see if we can do something proactive but I think its only from when they are a bit older.
This website Deafness research has lots of great information especially if your ds is in childcare, our nursery were able to pick up ds2's hearing difficultly before us as the noisy environment makes it more pronouced
best of luck, I hope that makes sense, if can help with any info (only from my experience) let me know xx
