Special exercise should not be forced upon young children. Physical culture, along with many other things intended for sedentary adults, should never be forced upon little folks who get all of the exercise they need in the many journeys they take building their blocks, sailing their boats, tearing down imaginary houses, making imaginary journeys--from morning until night the little feet are kept busy--never stopping until the sandman comes at sleepy time. Do not yourself attempt to stimulate a child who seems backward. Consult your physician. You had much better put a child out to grow up in the yard by himself with his sandpile than to force calisthenics or advance physical training upon him. BOW LEGS AND WALKING Do not attempt to hasten nature in aiding the child to walk. Let him creep, roll, slide, or even hunch along the floor--wait until he pulls himself to his feet and gradually acquires the art of standing alone. If he is overpersuaded to take "those cute little steps" it may result in bow legs, and then--pity on him when he grows up. Sometimes flat foot is the result of early urging the child to rest the weight of the body upon the undeveloped arch. A defect in the gait or a pigeon toe is hard to bear later on in life. A certain amount of pigeon-toeing is natural and normal. If the baby is heavy he will not attempt to walk at twelve months. He will very likely wait until fourteen or fifteen months. The lighter-weight children sometimes walk as early as eleven months, but they should all be walking at eighteen months, and if not, it is usually indicative of backward mentality. If the training of the bowels and bladder will replace the diapers with drawers, the baby will attempt to walk sooner than when encumbered with a bunglesome bunch of diaper between the thighs. The little fellow runs alone at sixteen months and thoroughly enjoys it, and the wise mother will pay no attention to the small bumps which are going to come plentifully at this particular time. SUMMARY OF BABY'S DEVELOPMENT He discovers his hands at three or four months. At six months he sits alone, plays with simple objects, grasps for objects, and laughs aloud from the third to the fifth month. He says "goo goo" at four or five months. At one year he should stand with support, listen to a watch tick, follow moving objects, know his mother, play little games, such as rolling a ball, should have trebled his birth weight, and have at least six teeth, and should use three words in short sentences. At eighteen months he should say "mamma" spontaneously, walk and run without support, should have quite a vocabulary, should be able to perform small errands like "pick up the book," and should have twelve to sixteen teeth. At two years he should be interested in pictures, able to talk intelligently, and know where his eyes, nose, mouth, hands, and feet are. At three years, he should enumerate the objects in a picture, tell his surname, and repeat a sentence with six words.
