9 months my baby how much weight?

A. At 9 months old, a healthy baby typically weighs around 7.5 to 10.5 kg, depending on birth weight, genetics, and overall health. Baby boys usually weigh slightly more than baby girls. If your baby is active, eating well, and growing steadily—even if they are on the lower or higher end of the range—there is usually no need to worry. It's best to track weight regularly using a growth chart and consult your pediatrician if the weight gain seems slow or irregular.
