What’s the Average Baby Weight by Month?

Normal growth is one of the best indicators of good health and nutrition. Normal heights and weights, however, are difficult to define. Short parents tend to have short children. Tall parents tend to have tall children. For any given height, an ideal weight can be determined from a growth chart. An infant with failure to thrive is underweight for his height. An obese child is overweight for his height.The average weight for full-term babies is 3.50kg.

Your baby’s physical development will be closely monitored at the developmental checks. Growth charts, which show the rate of growth expected for your baby’s weight and gestational age at birth, will be used to map her progress.

What factors affect baby weight?

Your newborn's baby weight is affected by many factor. These include:

  • Genetics: For example, the size of each birth parent.
  • Length of pregnancy: Babies born before their due date are often smaller. Babies born past their due date may be larger than average.
  • Nutrition during pregnancy: A healthy diet while pregnant helps your baby grow in your womb and beyond.
  • Lifestyle habits during pregnancy Smoking, drinking alcohol, or taking recreational drugs can affect your baby’s birth weight.
  • Your baby’s sex: It’s a small difference at birth, but boys tend to be larger and girls smaller.
  • Health conditions of the birth mother during pregnancy: Conditions such as diabetes, gestational diabetes, heart disease, high blood pressure, and obesity may affect your baby’s weight.
  • Your baby’s health: This includes medical issues such as birth defects and exposure to infection during gestation.

Issue with underweight babies

Babies may have trouble gaining weight for a variety of reasons. These include:

  • difficulty suckling
  • not getting enough daily feedings or calories
  • vomiting or gagging on milk
  • exposure to a prenatal infection
  • birth defects, such as cystic fibrosis
  • medical conditions, such as gastroesophageal reflux or congenital heart disease

Issue with overweight babies

If you have diabetes or gestational diabetes, you may have a larger baby. Above average-weight babies may require extra medical attention to make sure their blood sugar levels are kept in a normal range.

Your baby may also weigh more than average if you gain more than the recommended amount of weight during pregnancy. This is one of the reasons why it’s important to maintain a healthy diet while you’re pregnant.

Always follow your doctor’s recommendations.

Increased weight gain in babies in the first 6 to 12 months of life isn’t usually a concern.

Beastfed babies, in particular, often gain weight more rapidly in the first 6 months, then slow down after that. Occasionally, babies who weigh more may crawl and walk later than other babies do.

Your baby’s weight is one of many important indicators that help you and your baby’s doctor track your baby’s development. Gaining weight too slowly or too quickly can have long-term health consequences if not addressed.

However, a baby’s weight at birth doesn’t indicate what their weight will be as adults. Babies born prematurely or at a low birth weight can quickly catch up to their peers. Older babies and toddlers who are overweight can get help to reach and stay within a healthy weight range.
