Some things, although reprehensible from a four year old, when done by a two year old are adorable. Cussing (IMO) is one of these.
The other night we were trying to get the baby to say "ma-fa-seet!" (mother f-ing s**t), a favorite exclamation of Mr A and his friend Downtown MB. Of course, Ikaika was mimicking like a pro until I finally got the camera and then it all turned into hysterical laughing. This was the best video I got - he squeaks out a quick s-word right at the end.
So young...so impressionable...so quick to forget specifics!
