my baby weight was 3.025 at birth and now at 3 months 23 days she weighs 8.8kg is it ok or should consult pediatrician

A. Practically your child has gained 5.8 kg which actually much higher than the expected weight gain but here there’s a catch see you 1st to know the maximum weight gain a child can have in a month is 1 kg if it is more than that then we considered extra but you are the thing is that if the child is only an exclusive breastfeeding then it is a justified weight and nothing can be done but if you’re giving extensive formula or mixed feeding then you should definitely check with the doctor
