First Half of Third Year.—Children of this age should be put into night-drawers, cotton ones in summer and flannel ones either with or without feet, in winter. Tiny overalls or "rompers" are now used a good deal for both boys and girls while at play.

Second Half of Third Year.—Now he can walk in the street for a little while each day, even in winter, having his legs protected by warm leggings and with small rubbers for his shoes when the walks are at all damp. Woolen leggings should be used.

Children should not be allowed to race about in their night-drawers and bare feet. They should also have little wrappers and bedroom slippers.

[ALL ABOUT BABY 557]

What About the Nursery? The furnishings should be very simple. No unnecessary hangings or upholstered furniture. A large room, well ventilated and one in which the sun shines at some part of the day. The shades should be dark, but no extra hangings or curtains. Nothing should be allowed about the baby's crib but what can be washed. The air should be kept pure. There should be no plumbing, no drying of napkins or clothes, no cooking of food, and no gas burning at night. A small wax candle will do for all usual purposes.

What kind of heat is best? An open grate fire is best; next, heat from a Franklin stove. Steam heat is bad in a nursery. Never use a gas stove unless for a few minutes during the morning bath.

What should the temperature be during the day? From 66 to 68 degrees with the thermometer hung three feet above the floor. It should never be allowed above 70 F. At night, not below 65 F. during the first three months. After that it may go to 55 F., and after the first year it may go to 50 and even to 45 F.

Does the fireplace furnish enough ventilation? No, the principal ventilation must be from the windows.

How soon can you leave the windows open at night? Usually after the third month, except when the outside temperature is below the freezing point. How often should the nursery be aired? At least twice a day, after the baby has had his bath in the morning and also before putting him to bed for the night. This ventilation should be done thoroughly and the baby should be moved to another room. In the meantime, any time the child is out of the room it should be aired.

How can you ventilate the room at night? During the winter, while the baby is young, the sleeping room may be ventilated at night by opening a window in an adjoining room; or if the weather is not very severe, a window board may be used, or a frame on which has been tacked heavy muslin; this may be from one to two feet high and put into the window like an ordinary mosquito screen. In summer, a screen around baby's crib will furnish all needed protection from the open windows.
