Hi doctor, My son is walking with knees or legs wide apart. His age is 16 months+ . We have visited doctor 6days before he told it might be bow legs. And prescribed gemcol  twice daily and ultra vitamin d3 once weekly and to visit after a month.  Height is 84-86cm weight 11.6kg active to v active baby , all developments r good. Please suggest solution for us. My wife is still breastfeeding to my son. She is having thyroid problem so is it better to stop breast milk? As part of breakfast we give him 1 apple ,4-5 almonds,milk by making paste in mixer. And  mashed boiled white egg 4-5 times per week. For meals (3 times) we feed him with rice spinach chana dal and tur dal daily finely coocked in cooker Sometimes we add ghee Sometimes We add curries also whatever we make. We feed non veg like chicken, mutton, fish to him by mixing in his meals weekly twice.
