my baby is 1 yr old.. She started using walker when she was 5.5 months old.. Now I came to know that it's not good for babies legs if walker is used before 8 months.. I am worried if her legs are week. though she is now walking properly since 11 months but she often fell down and don't make proper balance.. plz let me know whether it's because of early use of walker ???if yes kindly suggest what can I do to make her strong.
