By what age should neonates typically regain their birth weight?

Neonates typically regain their birth weight by 10-14 days of age. After birth, it is common for newborns to lose some weight, generally around 5-10% of their birth weight, due to factors such as fluid loss and the adjustment to feeding. Most healthy infants will gradually begin to regain this weight as they adapt and establish regular feeding patterns, particularly following the transition from colostrum to mature breast milk or a feeding regimen in formula-fed infants. Establishing this weight by 10-14 days is a key indicator of good feeding practices and overall health, and it also serves as a reassuring sign for parents and healthcare providers that the infant is thriving. It is critical for infants to achieve this milestone to ensure ongoing growth and development support, thus solidifying the timeline of regaining birth weight as a vital aspect of neonatal care.
