Development of suck and swallow
1983
Herbst, John J.
Some of the aspects leading to the development of sucking and swallowing capabilities in neonates are reviewed and factors which affect the function and development of these capabilities are discussed. Non-nutritive (which develops first) and nutritive sucking can be altered by a number of factors, including introduction of a real or artificial nipple in infant feeding, the taste of various fluids, odor, infant hormones. Non-nutritive sucking by a premature infant of about 34 weeks does not imply that the infant will have effective nutritive sucking, and immediate gavage feeding may be necessary. Sucking beyond 20 minutes is likely to be non-nutritive. Furthermore, an excessive and prolonged delay in exposure to solid foods may lead to difficulties in swallowing once such foods are introduced. This review illustrates that there are regular patterns of development of sucking and swallowing in infancy and that these capabilities can influence infant nutrition. (wz)
