Another sleep-related advantage -- guessing this is focused on tech-related advantages, since it's in the HA/CI section, so I'll put it in those terms (even though I think this applies to any deaf kid, aided or not): we've gone to see movies and live plays at the theatre and if my daughter loses interest or it's a bit late for her, she can drop her coil or turn off her CIs altogether, cuddle up, close her eyes and sleep peacefully despite being in the midst of a loud performance .
Same with naps or early bedtime -- our household has never had to be quiet to avoid waking the baby, and our very loud dog barks freely.
She sounds so adorable! She will also have an advantage when she meditates. Will you teach her that later?
