I was just wondering, when it comes to language development, what you classify as a word your child knows? So for example my DD says 'ella' for elephant. Would you say that is a word she knows or not? What about if she knows a word, but just doesn't say it properly, for example she can't miaow, she says 'maow'? Or if she says a word that only we as her parents understand and other people do not, for example instead of thank you shes says 'gyou'? Then there are the words that sound nothing like the original word that she just picked up on, she says 'ga-la-lay' for climb. Just curious, I understand it isn't important, but was just wondering.
