Baby’s Health

- Weight
① A 3-month old baby’s weight has doubled from the time of birth. The speed of weight gain, which has been high, becomes gradual.
② Mothers usually evaluate the growth of their baby by observing if his weight is over/under the average groups. However, this is not that important. Rather, watch if your baby’s weight maintains a consistent level on the weight graph.
③ You wouldn’t get an accurate understanding of your baby’s growth by measuring your baby’s weight just once. Try measuring the range of weight gain on a regular basis.
