Final answer:
The mother's statement indicating that the toddler has a temper tantrum each time potty training is attempted suggests a misunderstanding of toddler developmental readiness for potty training. Not all toddlers are ready at the same age and could resist activities they are not prepared for.
Step-by-step explanation:
The question centers around toddler development and the expected behaviors of toddlers at various stages. Regarding the options provided by the mother in the scenario, the statement that necessitates further education is "She has a temper tantrum every time I put her on the potty chair." This shows a potential misunderstanding of the developmental expectations around potty training. It's important to note that not all toddlers are ready for potty training at the same age, and readiness can vary greatly from one child to another. Furthermore, toddlers are achieving a sense of autonomy and may resist activities they are not ready for or interested in.
From a developmental perspective, while toddlers may experience and express frustration in a variety of ways, including trying to escape their car seat, displaying separation anxiety at daycare, and scattering toys, expressing strong opposition to potty training may indicate that the toddler is not yet developmentally ready for this step. It is critical to understand that each child's pace in reaching developmental milestones like potty training can differ significantly.
