In the early weeks of the seventh month idle baby’s rollicking spirits were striking; in fact, she became for a time quite a little rowdy, ho-ho-ing and laughing in loud, rough tones, snatching this way and that, clutching at our hair with exultant shouts and clamor. In the latter part of the month, her manners were better—indeed, it was fully a year before I saw them as bad again; but she was much given to seizing at our faces, flinging herself at them with cries and growls (exactly as if she had been playing bear), and mouthing and lightly biting them. And indeed it must be confessed that while our baby’s behavior was often very pretty for weeks together, she had many fits of rough play and hoydenish spirits, and our faces and hair were never quite safe from romping attacks before she was two years old. This boisterousness was not overflowing spirits (real joyousness showed itself more gently) and I could never trace its psychological origin.

At intervals during the month, she continued to improve her bodily knowledge of herself, investigating her head and face and even the inside of her mouth, with her fingers; she rubbed her forefinger curiously with her thumb; she ran out her tongue and moved it about, trying its motions and feeling her lips. And the very first day of the month there had appeared that curious behavior that we call “archness” and “coquetting” in a baby (though anything so grown up as real archness or coquetry is impossible at this age), looking and smiling at a person who was somewhat strange, but very amusing, to her, then ducking down her head when he spoke, and hiding her face on her mother’s shoulder. Whatever the real reason of such behavior may be, there is plainly self-consciousness in it. So, too, when, at seven months old, she began to try deliberately to attract the interest of callers, wrinkling up her nose with a friendly grimace till they paid attention to her.

Both these forms of self-consciousness were common after this. Neither is what we could call human or rational self-consciousness. Any dog or kitten will show them. But they certainly are something more than mere bodily feeling of self. If we need a name for it, we might call it a beginning of intelligent self-perception, as distinguished both from bodily self-feeling, and rational self-knowledge—in which the mind, years later, will say to itself clearly, “This is I.”

We now began to suspect (as she ended her seventh month) that the baby was beginning to connect our names with us; and when we tried her by asking, “Where is grandpa?” or “mamma” or “aunty,” she really did look at the right one often enough to raise a presumption that she knew what she was about. The association of name and person was still feeble and shaky, but it proved to be real. In a few days it was firm as to grandpa (who was quite persona grata, because he built up blocks for her to knock down, and carried her about from object to object, to let her touch and examine); and in a week or two as to the rest of us.

Professor Preyer complains of teaching babies mere tricks, which have no real relation to their development; and certainly it is a sound rule that self-unfolding, not teaching, is the way in which a baby should develop in the earliest years. But Preyer’s baby learned to wave his hand, and play “patacake,” and show “How big is baby?” and the rest of it, just as other babies do; mammas and nurses cannot resist it. And as long as the babies like it, I do not see that it can do any harm, if it is not overdone. Besides, it may be said that these standard tricks are all closely related to the sign language, and so fall in well with the natural development at this stage. And again, the extreme teachability of the human child is his great superiority over the brute—all our civilization rests on it; and when the time comes that he is capable of receiving training, it may be as well that his power of doing so should be used a little, and that these simple gesture tricks of immemorial nursery tradition are good exercises to begin with. It is possible to make a fetich of “self-development,” beyond all common sense.

At all events, as our baby approached seven months old, her mamma had begun to teach her to wave by-by. For a couple of weeks, the mother would hold up the little hand and wave it at the departing guest, and before long the baby would give a feeble waggle or two after her mother had let go; next, she would need only to be started; and a week after she was seven months old she waved a spontaneous farewell as I left the room. There was a long history of the gesture after that, for it was lost and regained, confused with other hand tricks and straightened out, and altogether played a considerable part in the story of sign language and of memory, which I shall not have time to relate. But at all times it paid for itself in the delight it gave the baby: it reconciled her to almost any parting, and even to going to bed.

Her objection to going to bed, which had been evident since the fifth month, was because she thought sleeping was a waste of good playtime, not because she had any associations of fear and repugnance connected with it. She had never been left to cry herself to sleep alone, but was rocked and sung to in good old fashion. But she did show signs at this time of timidity and distress in waking from sleep, clinging piteously to her mother and crying. She had waked and cried alone a number of times, and, as I have already said, she seemed to have formed some associations of fear in this way. But I think there were deeper reasons for the confused distress on waking, which from now until halfway through the third year appeared at times.

I have spoken several times of the ease with which even we grown people lose our sense of personal identity; and changes in brain circulation make such confusions especially likely at first waking from sleep. With babies, whose feeling of identity is but insecurely established, this must be much more common; moreover, a baby’s conditions of breathing are less regular than ours, and it is probable that as he comes out of sleep, and the circulation and respiration of the waking hours slowly reestablish themselves, he has all sorts of queer, lost feelings. I was pretty sure, from our baby’s behavior I in the next two years, that she struggled back to the firm shores of waking consciousness through dark waters of confusion, and needed a friendly hand to cling to. This, I suspect, is the secret of the wild crying in the night, which doctors call “night terror”: it is not terror, I think, but vague distress, increased by the darkness—loss of self, of direction, of all one’s usual bodily feeling.

In these sensitive states attending sleep it is likely that some of the emotional conditions for life are formed, and the ties between mother and child knit firmest. My observation is that the one the baby loves most is the one that sleeps close by, that bends over him as he struggles confusedly back to waking, and steers him tenderly through the valley of the shadow of sleep; and next, the one that plays most patiently and observantly with him—not the one that feeds him.

In her absorption in her growing bodily activity, the baby had taken no marked steps in intellectual development, though in skill of handling, and in ability to understand what went on about her and put two and two together, she made steady progress. Early in the eighth month, some definite instances of this appeared. She showed a discreet preference at bedtime for anybody rather than her mother, and clung vigorously round my neck or her grandfather’s when that messenger of fate came for her. She dropped things to watch them fall, with a persistent zeal and interest such as she had not shown in earlier experiments of the sort. She knew what it meant if one of us put a hat on, and pleaded with outstretched hands and springing motion to go too. Once she found that in moving a long stick she was moving some twigs at its farther end, and kept up the experiment with curiosity.
