Ang baby mo ay healthy weight for 9 months! Mine was around 8.5kg at that age and the pedia said it's normal kasi bawat baby talaga ang sariling growth pattern nila, mas importante ang consistent growth trajectory kaysa sa exact number. At 98th percentile, your little one is thriving, which is great, pero just make sure hindi siya overfeeding especially if you're doing solids na, kasi sometimes we tend to push more food thinking mas malaki mas healthy e hindi naman necessarily.
