Amaia (who will be two in January) seems to have a slight issue distinguishing between dentals/alveolars and labials.
‘Hat’ becomes ‘hap’, ‘heart’ becomes ‘harp’, ‘my’ becomes ‘ny’, and ‘mine’ becomes ‘nine’.
It’s not systematic, however – she pronounced ‘daddy’ and ‘mummy’ correctly, and not as *’babby’ and *’nunny’.
Odd.
(And don’t ask me about the photo – it was the only photo suggested to me by Flickr when I put in labial and dental.)
