We've just had ds (5) at the hospital today for his second hearing test. There was no real improvement from the first test and he is apparently at the very bottom end of "normal" range. He's to go back in 6 months and if it gets worse then they will operate (grommets etc as they think glue ear type problem). If he stays as he is and they don't operate then is it likely to get better of it's own accord as he gets older?
