Gavin speaks pretty well (and a lot...) for his age, I think. I did notice, however, that he has a hard time saying aquarium and it sounds more like "Qwuary-Am". It's pretty cute and fairly subtle.
So off we went to the "Qwuary-Am" yesterday, just me and the boys. I like having a pass there. It's fairly cheap, not too far away, and you can go for just a short while because you know you can go back whenever. Plus, the boys love fish and it entertains them more than sometimes anything I can think of doing at home.
