Just curious, 13 mo dd hasn't said any words yet. I'm not worried, she's very bright in my eyes. Can do actions to songs without you showing her, blow kisses, make animal noises (not the right ones obviously, snails go roar) and lots more.
But at her 9 month review the health visitor said it would be a concern if she hasn't said mama/dada by 12 months. She's got a few months before it's a worry hasn't she?
