Kalau sis concern psl kurang kalsium, actually byk lg makanan sumber kalsium yg sis bole bg kat anak selain susu. Cheese, brokoli, ikan salmon sume tu sumber kalsium tinggi. And kalau ank xnk susu formula bole try bg susu dutch lady yg kotak kecil tu. Yg original bukan berperisa. Byk minum air suam bagus da tu 😎
