DS1 is 21 months and is getting grommets next week. He has glue ear in both ears and is down to 60% hearing because of this. He says a couple of words like duck, dock (he means clock), ear(which is meant to be cya when waving) and Nanna for banana. That's it really. He tries so hard to sing songs but its just jibberish. Does anyone have any positive stories about their LO's speech improving after grommets? Also what aftercare is there? Swimming and bathing?
