Just like any other human being, babies are also unique from each other. Each baby born grows differently under the factors like size, shape, genetics, the amount of food/breast milk he/she gets, and if either he/she gets breast milk or formula milk.
Breast milk is usually recommended since babies taking it grows and gains weight quicker on the first two months than those who take formula milk. Taking track on this major factor is indeed the gauge on the growth and weight of the baby since it’s the primary intake they have aside from vitamins and other supplements. From birth to his/her first month, a baby is expected to gain 2/3 to 1 ounce a day and to grow 1 to ½ inches during this span of time. Parents should not be alarmed of the sudden loss of weight during the first days of the baby’s life since it is normal and will gain weight on the succeeding days until they get back to their original weight.
From the first to the fourth month, a baby should gain weight of around ½ to 2 pounds and is expected to increase in length of about 1 to 1 ½ inches per month. During this time, the baby gets chubbier than their original form, but as the months go by and his/her activity increases, these fats will be replaced by muscle.
By the 6th month, it is expected that the weight of the baby should have doubled from his/her original weight. By the 12th month, the baby should have tripled that of his/her birth weight, and should have grown 9 to 11 inches from his/her length at birth.
By the 24th month, most infants have already gained four times their original weight and have grown 14 to 16 inches from their original birth length.
It is very important to have the weight gain and growth of the baby tracked by a pediatrician to see if it is normal and according to the scale and standard charts.
