The weight of a baby right after birth is an initial indicator of his or her overall well-being. In case of a full-term pregnancy, the typical newborn weighs about 3.2 kg (7 pounds).
It should be noted that all babies are unique in terms of their birth weight and other features. Such factors as genetics, the condition of the mother, and the age of pregnancy affect the weight of a baby.¹
What Is Considered a Normal Birth Weight?
- Low birth weight: Less than 2.5 kg
- Normal birth weight: 2.5 kg to 4 kg
- High birth weight: More than 4 kg
Doctors use these ranges along with other measurements to assess a baby’s health at birth.¹
Is It Normal for Newborns to Lose Weight?
Yes, it’s completely normal. Most newborns lose up to 7–10% of their birth weight in the first few days after birth. This happens as babies lose excess fluids and adjust to feeding.
By around 10–14 days, babies usually regain their birth weight if feeding is going well.¹
Why Birth Weight Matters
Monitoring your baby’s weight helps doctors:
- Assess overall health at birth
- Identify potential concerns early
- Track growth and development
- Ensure proper feeding and nutrition
Consistent weight gain over time is more important than the number on the first day.
