Final answer:
Loss of appetite is NOT a sign that an infant is ready to start solid foods. Increased interest in food, ability to sit up without support, and reduction of the tongue-thrust reflex are all signs of readiness for solid food introduction. The ocrrect option is 3.
Step-by-step explanation:
The question you've asked pertains to the signs that indicate an infant is ready to start eating solid foods. According to your textbook, the sign that is NOT indicative of an infant being ready for solid foods is loss of appetite.
In contrast, an increased interest in food, the ability to sit up without support, and the disappearance of the tongue-thrust reflex are positive signs that an infant may be ready to begin solid foods.
The tongue-thrust reflex, which is a natural reaction that helps prevent infants from choking, diminishes as they get ready for solids, making it easier for them to manage and swallow different textures. The ocrrect option is 3.
