Ka Ka and other stuff

Well it is official. Terrell has learned to say kaka. He has been getting much more vocal the last few days but I still don't understand half of what he is saying. For the record these are the words or phrases he says now:

• kaka
• Dada
• big bird
• all done
• want that
• what's that
• no
• uh oh
• oh no
• tea ( the kids loves decaf iced tea)
• mom mom ( but very very rare)

I am still worried that he isn't saying very much but Tony thinks he will be talking anyday now. He is 21 months old. Do any of you readers or lurkers have any ideas? I kinda want to call the doctor for a referral but at the same time I think he is fine. Who would have thought I would be excited that T can say kaka?
