It's too much from climbing to walking.
At first, the baby put his stomach on the ground and climbed forward with his hands. Then he can support himself on his limbs instead of sticking his stomach to the ground. Because most babies' arms are stronger than their legs, at first, many babies climb backwards.
Crawling gives the baby a new exciting feeling. He is free to go where he wants to go, but he also wants to learn to walk, because he sees adults around him walking on two legs. At first, he tried to hold something with his hands, such as a coffee table, a bed or your legs to support his body and keep his balance. Although standing alone is a prelude to learning to walk, many children are anxious or cry for help from adults because they are at a loss. At this time, you can tell him how to bend his legs and squat down and return to his original "low posture", so that he will be safer and less likely to fall.
When the baby is familiar with standing upright, he will tentatively take a small step. Of course, at first, he needs to learn to "borrow". He will understand that it will be easier to walk if he holds something in his hands to keep his balance.
Once self-confidence is established, the baby will loosen the hand holding things and walk completely freely. Walking is a skill that needs to be learned and practiced. Although he can't help holding on to something at first, and can only take a step or two, he will soon be able to "walk around".
