From the Research
No, there is no scientific evidence that propping up an infant to walk early causes bow legs. Bow legs (genu varum) are normal in infants and typically resolve naturally as children grow, usually by age 2-3 1. The development of a child's legs follows a predictable pattern, starting with bow legs in infancy and often progressing to knock knees before straightening out. Encouraging standing or assisted walking does not interfere with this natural process. Children will begin to walk when their muscles, bones, and nervous system are developmentally ready, typically between 9-18 months of age. While you should never force a baby to stand or walk before they show readiness, supporting them when they show interest is perfectly fine. If bow legs persist beyond age 3, are severe, occur on only one side, or are accompanied by pain or difficulty walking, consult a pediatrician as this could indicate an underlying condition such as rickets, Blount's disease, or other skeletal disorders that require medical attention. Some studies have investigated the relationship between physical activity and musculoskeletal problems, but none have found a link between propping up an infant to walk early and bow legs 2, 3, 4, 5. In fact, a study published in 2023 found that physical activity levels and quality of life are more important factors in determining musculoskeletal health than the timing of walking 1. Therefore, parents can feel confident in supporting their infant's natural development and encouraging physical activity without worrying about causing bow legs. It's always best to prioritize the child's individual developmental readiness and consult with a pediatrician if any concerns arise.
