My little guy did this, but it was pathological for him although he did not
always show his other signs of distress at the same time.  It considerably
worsened after a frenulectomy at 7 months but as he regained control of his
tongue and mouth afterwards, it completely disappeared a month later and I
haven't seen it since.
