Caleb Talk!

So, Caleb is 2 years old and he still doesn't have a big vocabulary.  We read to him and point things out, but we just don't hear many real words.  He says basic baby words like:  Momma, Dadda, Ball, No and Bye-bye!  One of his funny words is "Ca"  Anytime he sees a ceiling fan, he points at it and says, "Ca, Ca".  Don't know why he calls it Ca, but he does.  He's also been learning his letters and can actually say a few!  He has an AWESOME comprehension of what we say.  I love it when I say, "Does Caleb have to use the potty?" - he just puts that big smile on his face and walks right over to the potty!  I just wish he could use more real words.  He still points when he wants something.  We just try to redirect the way he expresses things like, "Oh, you want to go to sleep."  or "Caleb wants a drink".  Hopefully he'll repeat what we're saying!!!
