I know you're thinking "Dada" and "Mama", but no. He does say "dadadadadadada" and "mamamamamamama", but only at random. Until he actually attaches those sounds to my husband or myself instead of a pile of goldfish crackers, the piece of lint he's just picked up off the floor, or one of our guinea pigs, I don't think it really counts.
With these two words, however, he looks (and sometimes points) straight at the object while saying them, and never makes the same sounds in other contexts, so I know we've got actual language happening...
So, you ready for it?
Word number one? "Clock".
Word number two? "Button".
