5 months in a week and 8.7 kilo

ANA • Mom of 2💙 💝

Is it normal for my baby to have this weight? I mean he was born a little one. only 2.840 kilo. Till 3 months i breastfeed and half formula cause i didn't have too much milk. Now he drinks formula and i just started the cereal. I dont want him to overfeed but he really doesn't drink too much. And today he is 8.7 kilo. Nov 15th he will be 5 months.
