| Newborns can respond to differing tastes, including sweet, sour, bitter, and salty substances, with a preference toward sweetness. It has been shown that neonates show a preference for the smell of foods that their mother ate regularly, since the amniotic fluid changes taste with different foods eaten by the mother – as does breast milk. Studies have shown that infants who have been the recipients of positive touch experience more benefits as they develop emotionally and socially. Experiments have been done with infants up to four months of age using both positive touch (stroking or cuddling) and negative touch (poking, pinching or tickling). The infants who received the positive touch cried less often and also vocalized and smiled more than the infants who were touched negatively. |
