I find that I use a very different technique with my Baby Bass. Rather than holding it close to me like my DB, I hold it upright, often nearly at arm's length, so that I am plucking with my right hand quite close to where it would be on a DB.
I let the bass lean slightly forward, into my "fretting" fingers (you know what I mean), so that the weight of the bass supplies much of the pressure to hold the strings against the fingerboard.
All this, plus the amplification, means that I don't need to either hold the neck so firmly or pluck so hard.
I think of my Baby Bass as a cousin of my DB, not its brother. If I tried to play them both in the same way I'd hit the buffers pretty quickly.
Incidentally, if you YouTube the Baby Bass (there are plenty of brands besides KK) you'll soon notice how differently the salsa players handle it.
