The boy's ideal weight varies with age and height, and should be checked monthly by a pediatrician during the first year of life, as too low or too high a weight can impair his development and growth. Generally, weight gain is faster in the first 12 months, being considered normal, and as the boy grows, the tendency is for weight gain to be slower, as the child becomes more active, starts walking and spend more calories, slowing down the weight gain.
