Janet, Was the baby evaluated for tongue-tie? What you are describing might possibly resemble the "snap-back" of a tongue that is trying to extend but cannot maintain long enough for a good peristaltic wave; not every frenulum problem presents classically. This might be totally off-base, but it is a thought (I've had a wave of them lately). -Lisa ************************************************* Lisa Marasco, BA, LLLL, IBCLC [log in to unmask] / [log in to unmask] *************************************************
