During the first six or seven months, pregnancy, in itself, does not cause sleeplessness, but later, as a natural result of the enlargement of the womb, there are several disagreeable symptoms which may cause broken rest at night. In the later months the weight of the womb requires women to sleep on the side, and for some of them this position is awkward at first. Frequently the pressure makes it necessary to get up several times during the night to empty the bladder. In a few cases also the compression of the chest interferes somewhat with breathing. When insomnia is due to the pressure of the womb against neighboring parts of the body, it can be partially counteracted by getting into a comfortable position; but it is also necessary to have the surroundings as conducive to sleep as possible. Thus anyone will be much more likely to rest well if the bed-room is large and well ventilated, if the mattress is comfortable, and if the coverings are warm without being heavy. Finally, not the least important detail is to occupy a single bed, so that it is possible to turn over without fear of disturbing someone else. In most instances, however, the inability to sleep during pregnancy-- and indeed at any time--is due to a faulty frame of mind. With reference to the average man or woman, in his very helpful book "Why Worry," Walton says, "it is futile to expect that a fretful, impatient, and overanxious frame of mind, continuing through the day and every day, will be suddenly replaced at night by the placid and comfortable mental state which shall insure a restful sleep." Like everyone else, the prospective mother must stop thinking when she retires, otherwise the blood will not be diverted from the brain as it must be to fall asleep. To aid in bringing about this condition a number of expedients may be employed. For example, a warm bath, warm sheets, or a hot-water bottle placed against the feet all help to draw the blood from the brain to other parts of the body. Similarly, a warm glass of milk or a small portion of easily digestible solid food taken just before retiring will help to make one drowsy; on the other hand, over-eating at the evening meal or later is not an infrequent cause of wakefulness.
