my baby's birth weight is 3.16, she's 2 and half months old now. how much should be the ideal weight and when should i start other foods than breast milk?

A. Hello there ma’am please do not worry about it too much and baby should gain weight between 500 gms to 800 gms per month and also baby weight should be doubled the birth weight in one year. And also give baby breastfeeding exclusively for the first six months and after that six months give baby semi solid food. Take care
