At about six month my baby boy weighed 7.4 Kg now at 7 month he weighs about 8 kgs. His birth weight was 3.245 kg. is it normal not gaining weight fast after six month.

A. Consider these general guidelines for infant growth in the first year: From birth to age 6 months, a baby might grow 1/2 to 1 inch (about 1.5 to 2.5 centimeters) a month and gain 5 to 7 ounces (about 140 to 200 grams) a week. Expect your baby to double his or her birth weight by about age 5 months.
