My 15m old DD only says Hiya, Hello and Daddy regularly..
However she has said the following words very clearly a few times and then never again
Mummy (she said this for about a week)
Nanny
Grandad
Bye
Night night
Thank you
Love you
Her own name
And maybe some more that I've forgotten about.
She's a verrrry chatty girl though, just only in her own cute little language! You can tell she's trying to say something as she will repeat 'sentences' in her own golly golly way.
Is this normal for them to do this?
