My baby is 2 month 10 days old her birth weight was 3 kg and now she is 5.3 kg is it a healthy weight gain?

A. From birth to 1 year, they will triple their birth weight. On average, the first three months of life will bring about an ounce of weight gain per day. Under normal circumstances, the weighing a baby receives during regular doctor visits will be enough to observe normal growth and gain.
