Babies first words

The first words of every baby are very similar, and there's a reason for most of languages have "da-da" or "pa-pa" as the father's name :)

Our wee one said firsts "da-da", then he went to "ta-ta" almost whispering to end up with a proper "pa-pa" that was soon followed by "ma-ma". He hasn't learn the famous "no-no" but I am not sure if I'm looking forward that moment or I prefer to delay it as much as possible :P
