The child is already beginning to realize that he is a separate person - this is manifested in the fact that he can notice and show himself in the mirror, recognize him in a photo or video.

Caring for a 9 month old baby

Caring for a 9-month-old child – without any special features or peculiarities. It is also necessary to pay attention to the baby's hygiene, especially before changing the diaper. Full bathing with soap products is recommended no more than twice a week. If the little one likes being in the bath, it is allowed to have daily water treatments before dinner (without soap and shampoos).
At this age, parents begin to think about purchasing a walker; they think that this way the child will learn to walk quickly and correctly. The opinions of experts about such a product cannot be called unambiguous.
However, most experts argue that walkers can cause some harm to the child’s musculoskeletal system if he has not yet learned to hold his back straight.
Even the most expensive and high-quality walkers will create additional stress on the spine, causing its curvature in the future.
In addition, using such a device will not teach the child balance. In a walker, he would rather hang than stand upright. This will result in the child having difficulty learning to walk independently by 12 months. Also, some experts note an increased risk of developing flat feet.
