New born baby weight in kg

The average weight of a newborn baby varies slightly depending on the gestational age and sex of the baby. Here are the average weights for newborn babies:

• Boys:
  • Born at 37 weeks: 2.5-3.5 kg (5.5-7.7 lbs)
  • Born at 38 weeks: 2.7-3.7 kg (6-8.2 lbs)
  • Born at 39 weeks: 2.9-3.9 kg (6.3-8.6 lbs)
• Girls:
  • Born at 37 weeks: 2.3-3.3 kg (5-7.3 lbs)
  • Born at 38 weeks: 2.5-3.5 kg (5.5-7.7 lbs)
  • Born at 39 weeks: 2.7-3.7 kg (6-8.2 lbs)

It's important to note that these are only averages, and newborn babies can weigh anywhere from 1.5 to 4.5 kg (3.3-9.9 lbs) or more. Factors such as the mother's weight, height, and overall health can influence the baby's birth weight.

Here are some general guidelines for newborn baby weights:

• Low birth weight (LBW): less than 2.5 kg (5.5 lbs)
• Very low birth weight (VLBW): less than 1.5 kg (3.3 lbs)
• Extremely low birth weight (ELBW): less than 1 kg (2.2 lbs)
• Small for gestational age (SGA): below the 10th percentile for weight at a given gestational age
• Appropriate for gestational age (AGA): within the 10th to 90th percentile for weight at a given gestational age
• Large for gestational age (LGA): above the 90th percentile for weight at a given gestational age

It's always a good idea to consult with a healthcare provider if you have any concerns about your baby's weight or overall health.
