First word?

Samara has been babbling up a storm lately...mamama, dadada, bababa, etc. BUT, I'm not convinced she knows what she's saying nor does she seem to use the "words" correctly. So we still do not have a first word (which means there's time for MAMA to come out of her mouth unexpectedly!). It does seem like she's working on 2 though. There is this blue ball, which if you've been over to our place, you know the one! She just loves it and whenever she digs it out of her basket, she proudly holds it up in the air like it's a trophy. She says "BA!" when she does it so I'm thinking she's trying to say ball. The 2nd word is banana. She is hugely fond of bananas and we end her supper with that for dessert every night. I get out a banana and ask her if she wants some and she seems to say "anana". One of the picture books we have has a page with bananas on it and when Shawn was reading it to her the other day, he flipped to that page and she said "anana". But then the other day she called one of the cats "anana" so who knows?!
