Can a baby get rickets by walking at an infant age?

Rickets is primarily caused by a deficiency in vitamin D, calcium, or phosphate, rather than by the act of walking itself. Infants typically begin to walk between 9 and 15 months, and walking at this age does not contribute to the development of rickets. However, if a baby has nutritional deficiencies that lead to rickets, any weight-bearing activity, including walking, may exacerbate existing bone weakness. It's essential for infants to receive proper nutrition to support healthy bone development.
