Too short an interval between childbirths would also seem to be an infringement on the rights of the child as well as of the mother. Thus Dr. R. J. Ewart, (“The Influence of Parental Age on Offspring,” Eugenic Review, Oct., 1911) finds that children born at intervals of less than two years after the birth of the previous child still show at the age of six a notable deficiency in height, weight and intelligence, when compared with the children born after a longer interval, or even with first-born children. P. 166.
