Sometimes mothers wonder about the murmuring sounds the baby is making while breastfeeding. Is this usual, they wonder?
Many years ago an American radio doctor called Richard Applebaum became interested in the murmuring sounds babies often make while breastfeeding. So he invited mothers from across the US to send him tapes of their babies' sounds. I don't still have his book but, from memory, he ended up with over 2,000 recordings. Interestingly, some mothers sent recordings of the same baby drinking from a bottle, and remarked that it was only at the breast that these sounds were made.
I offer this information as reassurance to new mothers that this behaviour is normal. The 'how' and 'why' of it I don't know. Why don't babies do this when they are experiencing other oral satisfaction, on a bottle or dummy (pacifier)? Is it related to the unique mechanics of at-breast feeding? Is it more innate than that? Perhaps the reason doesn't matter, but it is lovely that some mothers come to see it as a sign of their baby's pleasure.
