Eh, at 2 years old sebenarnya dia boleh mula transition ke susu lembu biasa atau high-calcium milk, tapi kalau nak stick dengan formula, most brands punya iron content dah cukup untuk usia tu, just check the nutrition label yang iron content dia around 8-10mg per serving. A few of us mum friends, kami prefer brands macam S-26 Progress or Enfagrow A+ sebab they're fortified with iron and other nutrients dia kena, tapi honestly susah nak compare sebab setiap brand punya formula slightly different. Kalau dia ada signs of iron deficiency (macam tired, kurang active), better tanya paediatrician dia mana one yang paling suitable untuk anak kita specifically, because every kid's needs tu berbeza-beza.
