SITTING ALONE
At four months the normal baby will hold up his head; and if he is supported at the back with a pillow, he will sit erectly—holding his head up—at six months; while at eight months or not later than nine, the normal child should sit alone on the floor with no support. Later in the ninth month he often manifests a desire to bear his weight upon his feet. Care is here urged that the mother protect the little fellow at this time and not allow him to rest his weight upon his feet but a moment or two at a time.
He will reach for a ball suspended from the top of his carriage or bed as early as the fifth month. About this time he discovers his toes while in his bath. He will handle a rattle at six or seven months, and shows delight in such toys.
