My baby is 2 and half months old...His weight is 3.4kg and birth weight is 2650gm...Is it normal?

A. It is just hundred grams less if I look at it because a minimum weight gain as per doctor should be 400 g in a month it is 350 g for a child every month which is decent enough so don’t worry about it if you required you can also introduce formula feeding to the child at least one time in the day hopefully that is going to help in making it better
