Hai! Honestly ni normal phase je at 3 months, babies sometimes jadi lebih efficient at nursing so feeding time jadi shorter and less frequent, bukan bermakna dia kurang dapat susu. Tapi since you're worried about milk intake, best to check with your pediatrician or lactation consultant to weigh baby and confirm dia gaining weight properly, that's really the only way to know for sure. Kalau baby alert, wet diapers normal, dan weight gain OK, dia probably fine je, tapi peace of mind tu priceless kan, especially as first-time mum.
