POOJA KOTHARIMom of a 8 yr 5 m old boy2 years agoA. The average weight for a 4-month-old baby is 14.2 pounds for girls and 15.4 pounds for boys; the average length (aka height) is 24.4 inches for girls and 25.2 inches for boys.
Of course that doesn’t mean your 4-month-old should weigh and measure exactly that. Remember: Healthy babies tend to follow a natural growth curve, staying within the same percentile as they grow older, and it’s the growth itself that’s an indicator of healthy development—not the actual percentile.
Baby probably has gained an extra 1 to 1.25 pounds in the past month, and they’re likely to go through a growth spurt this month.
