Virtually all but my newest massage clients are very aware of my passion for birth and all things birth related. They all know when I am on call for a birth and enjoy hearing the happy news when I am celebrating the arrival of a new baby. One of my clients in her 70's had an occasion recently when she was caring round the clock for her new great nephew.  Mom had left a supply of pumped milk and my client was a bit alarmed by the 8 week old waking overnight every 2 hours for a feeding.  I enjoyed explaining how very tiny a young baby's tummy is, how easily and quickly mom's milk is digested and how breastfed babies tend to wake more frequently to eat (which seems to be a plus as far as SIDS is concerned). I mentioned my recently discovered teaching tool learned at my PfB training where we strung a necklace of 3 beads, one the size of a marble, one the size of a walnut and one the size of a ping pong ball and explain how they nicely depict the size of an infants stomach capacity in the early days and weeks. She was so impressed to hear all of the details. More than once during my PfB training it was suggested that I might consider teaching a grandparents class.  Now, the idea is stewing!
