gd mrng sir.. sir, my baby 8 months old ..but her weight is 6 and half kgs..is there any problem..?

A. No that is normal, While all babies may grow at a different rate, the following is the average for boys and girls 7 to 9 months of age: Weight: average gain of 1 pound each month; boys usually weigh about ½ pound more than girls; 2 times the birth weight by 4 to 5 months and 3 times the birth weight by 1 year.
