my baby born with 2.450 then her weight 2kg now my baby girl is 25 days old and her weight is 2.7 kg it's normal?

A. hello yes it os absolutely normal and is nothing to worry about and baby gaining a minimum of six hundred grams to 800 grams per month then it is a good weight gain and is absolutely nothing to worry about and in the first month u cannot expect much weight gain as babies birth weight will resuce and then start gaining
