12 weeks new born baby weight

According to the World Health Organization (WHO) growth charts, the average weight of a 12-week-old newborn baby is around 6.5-7.5 kg (14.3-16.5 lbs). However, it's essential to note that every baby is unique, and their weight can vary depending on several factors, such as:

  1. Gestational age: Babies born prematurely may weigh less than those born at full term.
  2. Birth weight: Babies with a higher birth weight may gain weight faster or slower than those with a lower birth weight.
  3. Breastfeeding: Breastfed babies tend to gain weight at a slower rate than formula-fed babies.
  4. Genetics: Babies with a family history of being heavier or lighter may follow a similar pattern.

Here's a rough estimate of the average weight range for 12-week-old newborn babies:

Keep in mind that these are general guidelines, and it's always best to consult with your pediatrician or healthcare provider for personalized advice and guidance on your baby's growth and development.
