[lojban-beginners] suck

[MorphemeAddict@wmconnect.com]

Is the following a correct way to translate "The baby sucks its mother's breast."?

le cifnu cu sakci le jipno be le tatru be le ra mamta

The meaning as given in my gismu list list seems really inappropriate for this sentence, but I can't think of a better word to use.  In fact, I can't come up with a decent sentence using "sakci" at all.  Any suggestions?

sakci = x1 sucks/is suction/vacuum/relatively low pressure of fluid/gas x2 relative to high pressure x3.

(Apparently the gismu keyword "sucks" sucks.)
