hi . my baby's birth weight is 2.6kg and now she is 3 months 17 days old her weight is 5.00kg . is it fine ?

A. Typically, a baby's weight doubles within their first 4 to 6 months of life and triples in their first year. For instance, a baby born weighing six pounds would typically weigh about 12 pounds by the time they were 6 months old and about 18 pounds by the time they turned 1. Slow weight gain is not always a concern.
