When my son began to talk, he mispronounced many words and struggled to make certain sounds.  Not out of the ordinary for a baby, and it was sweetly reminiscent of my little sister, Mary, who spoke with a slight lisp and chewed her words when she spoke in a way that mesmerized all she met.  Mary’s little lisp was cute and captivating when she was a child, and she eventually grew out of it (for the most part – I can still hear it when she is really tired).
