Aduh, 62cm at 6+ months memang agak kecil ye, tapi jangan worry dulu, setiap baby grow at their own pace, and some are just naturally petite! Best thing is to check with your pediatrician to make sure everything is okay, then maybe ask if there's anything nutrition-wise you can improve, sebab proper feeding really does help. A few of my mum friends yang worried about height, doctor recommended ensure baby getting enough milk, good weaning foods with protein, and tummy time to help development overall, but doctor consultation is important first, okeh?
