Conditions. 1. Bed alone. No one can sleep as comfortably or restfully with another person as alone. With little children, moral as well as physiological possibilities are to be considered.
2. Room alone, if possible, especially for children under six, that they may not be disturbed.
3. Outdoors if possible, on a sleeping porch, with bedding protected from dampness, and provision made for first warming the bed at night in cold weather.
4. Room cool and with current of outside air, if sleeping indoors. Temperature not above 60° F. and may be as low as 50° F. to advantage for normal children over six months, or 32° F. without harm, with ample bedding and warm night clothes. Warm wrapper or shawl should be provided to wrap around the child when taken out of bed.
5. Children beyond infancy (1½ years) should have their supper an hour before bedtime until eight or nine years of age, and thereafter two hours before bedtime. Children should be taken up for the toilet at a regular hour, either nine or ten o’clock, until six or eight years of age, to prevent bed-wetting or disturbed sleep.
6. Every condition should be provided for complete relaxation and sound sleep, not light semi-sleep. Among these conditions, besides the foregoing, are:
Lights extinguished in sleeping room;
Stationary bed that does not rock;
