Why do babies urinate when they hear “SHHH..” sound?
Babies may urinate when they hear the “SHHH…” sound due to a reflex known as the startle or Moro reflex. This reflex is an involuntary response characterized by an abrupt extension and spreading of the arms and legs, followed by a cry. The startle reflex is present in newborns and typically diminishes over time as the baby’s nervous system matures.
During the startle reflex, the baby’s heart rate and breathing may increase, and as a result, the pressure in their bladder may rise. This increased pressure can trigger the baby to urinate. It’s important to note that not all babies will exhibit this response, as each baby is different and may have varying sensitivities to different stimuli.
Another factor that may contribute to a baby urinating when hearing the “SHHH…” sound is conditioning. If a baby repeatedly associates the sound of “SHHH…” with the act of urinating due to previous experiences, they may display this response as a learned behavior.
It is worth mentioning that there isn’t a definitive scientific consensus on the exact reasons why some babies urinate when they hear the “SHHH…” sound. Further research is needed to fully understand the underlying mechanisms responsible for this response.
