Eh jangan risau sangat lah! 8kg at 2 bulan 14 hari memang on the heavier side, tapi growth pattern anak lelaki dan perempuan pun lain-lain, dan genes juga main peranan besar. A few of my mum friends pun ada baby yang chubby at this age tapi by 6-12 months growth dia stable je, depends on milk intake, genetics, semua factor. I think best to confirm with your pediatrician during the next checkup, dia boleh cross-check against the growth chart dan make sure everything else is on track, then you dapat peace of mind for sure!
