Alah, kuat makan memang bagus tapi 4oz setiap kali mungkin agak banyak untuk baby 6 bulan, biasanya start dengan 2-3oz and slowly increase based on baby's hunger cues, lah. A few of my mum friends ada baby yang kuat makan jugak, tapi dorang follow pediatrician's guidance untuk portion size sebab baby stomach still small, plus overfeeding boleh cause discomfort or reflux. Better check with your doctor about the right amount for your baby's weight and development, they can guide you properly on this one!
