Toddler hearing aids

Morning,

Our gorgeous 2.5 year old who has been fighting with enormous adenoids most of his life is being lined up for hearing aids as a (likely temporary) support as no further surgical or medical options are open to him right now but we need to support his communication development.

We're a bit upset, largely because we thought grommets etc would still be an option but we have to wait.

Does anyone have any experience of a toddler getting hearing aids, how it works, how they adapted etc?
