Introduction
Hey readers! Your little one is growing up so fast, and it’s perfectly normal to wonder about their weight. As they get older, it’s essential to know what is considered an average weight for a 4-month-old baby. In this article, we will explore everything you need to know about the average 4 month old weight, including growth patterns, factors that influence weight, and ways to track your baby’s progress. By the end, you’ll have all the information you need to ensure your little one is thriving and growing healthily.
Average Weight for a 4-Month-Old
According to the World Health Organization (WHO), the average weight for a 4-month-old baby is:
- Boys: 6.7 kg (14.8 lbs)
- Girls: 6.2 kg (13.7 lbs)
However, it’s important to note that these are just averages. Every baby grows at their own pace, so don’t worry if your baby is slightly above or below these numbers. As long as your baby is following their growth curve and gaining weight steadily, they are likely doing just fine.
Factors Influencing Weight
Several factors can influence a baby’s weight, including:
Genetics
Your baby’s genes play a significant role in their weight. If you or your partner were small or large babies, your child is likely to be similar.
Birth Weight
Babies who are born with a healthy birth weight tend to gain weight more rapidly than those who are born premature or underweight.
Feeding Practices
Whether your baby is breastfed, formula-fed, or a combination of both can also affect their weight. Breastfed babies tend to gain weight more slowly than formula-fed babies. However, both methods provide the necessary nutrients for healthy growth.
Activity Level
More active babies may burn more calories and therefore weigh less than less active babies.
Tracking Your Baby’s Weight
It’s a good idea to track your baby’s weight regularly to ensure they are growing and developing on track. You can do this at home using a baby scale or at your child’s doctor’s office during their regular checkups.
When weighing your baby at home, be sure to do it at the same time each day, preferably before a feeding. This will help you get the most accurate reading.
Growth Patterns
Babies typically gain weight rapidly during the first few months of life, then their growth rate slows down slightly as they get older. Between 4 and 6 months of age, babies typically gain about 5-7 ounces (140-200 grams) per week.
It’s also important to note that babies may experience periods of rapid growth, known as growth spurts. During these times, your baby may seem to be eating more than usual and gaining weight quickly. Growth spurts are normal and typically last a few days or weeks.
Concerns about Weight
If you are concerned about your baby’s weight, it’s important to talk to your doctor. They can assess your baby’s growth pattern and determine if there are any underlying medical conditions that need to be addressed.
Underweight
Babies who are underweight may not be getting enough to eat or may have a medical condition that is affecting their ability to absorb nutrients.
Overweight
Babies who are overweight may be consuming too many calories or may have a medical condition that is causing them to gain weight too quickly.

However, it’s important to remember that every baby is different, so don’t worry if your baby is slightly above or below the averages. As long as your baby is following their growth curve and gaining weight steadily, they are likely doing just fine. If you have any concerns about your baby’s weight, be sure to talk to your doctor.
