When advising caregivers about introducing solid foods to an infant, which sign of readiness is essential?

The essential sign of readiness for introducing solid foods to an infant is that the child is able to sit in a high chair. This indicates that the child has developed sufficient head and neck control, which is crucial for safe eating. Sitting upright helps prevent choking and allows the infant to swallow food more effectively. At this stage, the infant is generally capable of handling solids and has reached a level of physical development necessary for transitioning from a solely liquid diet.

In contrast, other options reflect conditions that are not appropriate for introducing solids. For example, if a child regularly refuses solids or shows no interest in food, this suggests that the infant may not yet be ready for this dietary transition. Similarly, a child sleeping through feedings may indicate a lack of readiness or interest, which is not a good sign when considering the introduction of solid foods. It's essential to ensure that infants are developmentally prepared, and the ability to sit in a high chair aligns with these readiness requirements.
