Discuss the sensitivity of neonates to different tastes.
What will be an ideal response?
Answers will vary. Neonates are sensitive to different tastes, and their preferences, as suggested by their facial expressions in response to various fluids, are like those of adults (Beauchamp & Mennella, 2011). Neonates swallow without showing any facial expression suggestive of a positive or negative response when distilled water is placed on their tongues. Sweet solutions are met with smiles, licking, and eager sucking (Rosenstein & Oster, 1988). Sour fluids elicit pursing of the lips, nose wrinkling, and eye blinking. Bitter solutions stimulate spitting, gagging, and sticking out the tongue.
