It is normal for the newborn's legs to bend inward, which is an extension of the baby's habit of curling in the mother's body.
Guiding opinions:
When the baby is older, it will gradually return to normal. O-leg means that the leg bones of the baby are obviously bent inward when walking, and the knees are not close together when standing, and the toes are inward in a figure of eight. O-leg is a symptom of rickets.
