Ang normal na timbang ng baby sa 8-9 months ay around 7-9 kg, pero honestly it really varies, bawat baby ay may sariling growth pattern kaya huwag mag-alala if slightly lower or higher pa yan. A few of us moms noticed na ang aming babies ay different lahat, some were chubbier at iba naman slimmer, and that's completely okay as long as healthy sila at kumakain well. Best talaga na i-check with your pediatrician during regular check-ups para sure na on track lang ang growth ng baby mo, dahil sila ang makakapagsabi ng tama based sa curve ng baby.
