#asktheexpert what should be the weight of 5 months old baby girl born with birth weight 2.1 kg

A. hi dear 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.
