Of course, where the child can be fed regularly, this helps the mother to regulate her own habits, and is comforting to all concerned. Therefore, nurses should not lack in determination to encourage such a system. But no such regularity should be insisted upon where both baby and mother suffer during the interval when nursing is denied; the former, hungry and crying lustily, and the mother under a nervous strain that is harmful to both. Let there be no hard-and-fast rules. Babies who feed as often as they feel like it (being allowed proper, though not necessarily long, intervals for digestion) generally suffer no ill effects and are healthy and strong. Mother’s milk, the natural feeding, should always be given, rather than any artificial food, when the supply is sufficient and good. OBSTETRIC SUPPLIES. =Solutions:= Antiseptic solutions.

FETAL CIRCULATION. _From Kimber’s Anatomy._ The peculiarities of the fetal circulation, leaving details aside, are: the direct communication between the two auricles of the heart, through an opening called the foramen ovale; the communication between the pulmonary artery and descending portion of the arch of the aorta, by means of a tube called the ductus arteriosus; and the communication between the placenta and the fetus, by means of the umbilical cord.
