Hi! At 6 months, babies usually weigh around 6-8 kg depending kung exclusively breastfed or formula-fed sila, and of course every baby is different, ang amin nang pinakamaliit sa edad na yan kaya mas mababa pa hehe. Best talaga na i-check with your pedia sa regular checkup para sure na on track ang baby mo, kasi alam nila ang growth chart at kung paano kumain and develop ang little one mo personally.
