My baby's weight is Kilo 9 gm but her birth weight was 2 kilo 2 gram but now she is 4 kilo 8 gram above and she is now 5 months completed what is the right weight can you please tell me if this is normal

A. Actually minimum weight gain should be 500 g to 1 kg it can reach so if I just go for the maximum side it should be 7 kg by completing the time of five months so are you giving formula milk if your child is getting this weight with the breastfeeding then it is okay not a problem but if it is with formula then I think it’s better to check with your doctor once
