How do baby learn how to walk by themself?
Babies watch people walk around and they usually want to walk like everyone else. In some situations, though, babies don't care, so their parents will stand a few feet away and hold out their arm saying, "Come here, baby! Come on!." The baby will try to move towards the mother or father. Soon, they will learn to walk, if a baby is two and a half and still won't try (or will try and fail) I would get the toddler checked.
