I’ve seen a baby put his entire fist in his mouth and suck on it. I don’t get it. Is a baby’s fist smaller than their mouth…or does the mouth open wider than their fist? It was pretty funny/interesting to watch.

My son did that for quite some time. It is pretty funny. The mouth sure opens wider than their hand and/or fist.
