If your ten-month-old baby has an inward curvature, it is recommended that you seek medical attention to clarify the cause, and then follow up with observation, medication and orthodontic treatment. 1. Follow-up observation: Ten-month-old babies usually just start to learn to stand up, at this time the legs are weak and difficult to support the upper body, so they may appear to have internal eights, which can be evaluated by the doctor and then followed up for observation. 2. Medication: If your baby lacks vitamin D or calcium during growth and development, he or she may develop an inward curvature. You can further improve the X-ray examination of both legs, blood calcium or vitamin D level, and take vitamin D and calcium orally as prescribed by your doctor. 3. Corrective treatment: When the baby sleeps, use soft cloth or bandage to tie the legs together, and the tightness should be appropriate to correct the condition of internal eight feet caused by knee valgus. It is recommended that babies with internal eight feet should consult a doctor in time and under the guidance of the doctor to avoid the adverse consequences.
