But this difficulty comes later. Now we are concerned with a three-months-old baby. At this stage the child is usually able to balance his head, to sit up against pillows, to seize and grasp objects, and to hold out his arm, when he wishes to be taken. Although he may have made number of efforts to sit erect, and may have succeeded for a few minutes at a time, he still is far from being able to sit alone, unsupported. This he does not accomplish until the fifth or the month. [Sidenote: Danger of Forcing] There is nothing to be gained by trying to make him sit alone sooner; indeed, there is danger in it--danger in forcing young bones and muscles to do work beyond their strength, and danger also to the nerves. It is safe to say that _a normal child always exercises all its faculties to the utmost without need of urging, and any exercise beyond the point of natural fatigue, if persisted in, is sure to bring about abnormal results_. [Sidenote: Creeping] The first efforts toward creeping often appear in the bath when the child turns over and raise, himself upon his hands and knees. This is sign that he might creep sooner, if he were not impeded by clothing. He should be allowed to spread himself upon a blanket every day for an hour or two, and to get on his knees as frequently as he pleases. Often he needs a little help to make him creep forward, for most babies creep backward at first, their arms being stronger than their legs. Here the mother may safely interfere, pushing the legs as they ought to go and showing the child how to manage himself; for very often he becomes much excited over his inability to creep forward. The climbing instinct begins to appear by this time--the seventh month--and here the stair-case has its great advantages. It ought not to be shut from him by a gate, but he should be taught how to climb up and down it in safety. To do this, start him at the head of the stairs, and, you yourself being below him, draw first one knee and then the other over the step, thus showing him how to creep backward. Two lessons of about twenty minutes each will be sufficient. The only danger is creeping down head foremost, but if he once learns thoroughly to go backward, and has not been allowed the other way at all, he will never dream of trying it. In going down backward, if he should slip, he can easily save himself by catching the stairs with his hands as he slips past. The child who creeps is often later in his attempts to walk than the child who does not; and, therefore, when he is ready to walk, his legs will be all the stronger, and the danger of bow-legs will be past. As long as the child remains satisfied with creeping, he is not yet ready either mentally or physically for walking. [Sidenote: Standing]
