Which of the following is an indicator for physiological readiness in toilet training?

The recognition of the need to toilet train is a crucial indicator of physiological readiness because it signifies that the child is developing a sense of bodily awareness and control over their elimination needs. This awareness is essential for successful toilet training, as it indicates that the child can identify when they need to use the toilet and can communicate that need effectively. Physiological readiness encompasses the maturity of the child's bladder and bowel function as well as cognitive understanding, both of which are essential for recognizing and responding to the signals that indicate a need to urinate or defecate.

In contrast, while consistently asking to use the bathroom and demonstrating interest in potty training are important behaviors that can reflect readiness, they may not solely indicate physiological readiness without the underlying recognition of bodily cues. Additionally, the ability to sit independently, while beneficial for using a toilet, does not directly relate to a child's readiness to recognize their need to go, which is a fundamental aspect of successful toilet training.
