What is the expected growth velocity for infants aged 0-4 months?

The expected growth velocity for infants aged 0-4 months is indeed between 23-34 grams per day. During this early period of life, infants experience rapid growth as they adapt from the intrauterine environment to gaining nutrition externally. This high growth rate is crucial for their overall development, supporting their physical needs as they establish feeding patterns and begin to build their body mass.

During this stage, infants typically double their birth weight by around five months of age due to this substantial daily weight gain. Adequate weight gain is a vital indicator of infant health and nutrition, reflecting their intake and metabolic needs. Thus, the range of 23-34 grams per day accurately captures the expected growth velocity for the majority of healthy infants during this critical period. This information is essential for pediatric assessments and can guide healthcare providers in identifying potential growth issues early.
