The time for each baby to start standing and walking varies greatly. Some babies can walk when they are 9 months old, and some babies will not start walking until 12~ 13 or even later. This is mostly related to many factors, such as the baby's own development, genetic factors, sports training opportunities, diseases, seasonal effects, etc. Some babies are afraid after falling when they are just toddlers. It is a great progress for the baby to learn to walk from lying to standing, which is of great significance to the baby's physical development and psychology. Therefore, mothers should teach their babies to walk in time and create some conditions for them to learn to walk, such as preparing walkers, fences, trolleys and push-pull toys. And often let the babies help their mothers walk. In addition, the addition of complementary food should be comprehensive and balanced, and the baby should be tested for trace elements, whether it is lacking or supplemented.
