Understanding baby weight gain

Baby Weight Gain Chart 1

Babies tend to lose their initial birth weight by 10% in the first few days after birth. Parents might start developing apprehension and angst because of this. However, they should understand that these transformations are very normal so they should not be alarmed.

When babies lose their initial weight it’s because their birth fluids which are no longer indispensable are being expelled from their bodies. In about 10-14 days, the child should start regaining weight at the rate of 140-210 grams per week in the first three months. In the event of this not happening, the parent should consult a doctor.

From 3-6 months, the baby’s weight starts slowing down to 105-147grams per week, and finally between the 6th-12thmonth the weight increases by 70-91 grams per week. Babies who exclusively feed on breast milk gain weight slower than artificially fed babies after 3-4 months. However, those who are breastfed are less likely to become obese than formula-fed infants.

The mother’s diet and health during pregnancy and also during breastfeeding contributes to the baby’s weight. Mal-nourished mothers and those who take alcohol and smoke cigarettes will pass down little nutrients to their infants, therefore, making the baby gain weight slowly.

Diabetic mothers will tend to have very heavy babies- bigger than the normal weight.  In the baby weight gain chart, genetics plays a big role in whether the baby is going to be heavy or small.

Weight gain according to baby’s height

Although growth patterns in infants tend to vary, when one looks closely at how they progress in growth they all happen to follow a similar pattern. Most newborn babies range between 18-22 inches and their head circumference being 12 inches. From birth up to the 6th month, they add half to one inch monthly with a weight gain of 140-200 grams per week. In the 6th -12th month they gain one centimeter each month with a subsequent weight gain of 85-140 grams per week.

However, as a parent, when you realize your child does not fall under any of these categories, you should not be dysphoric because there are a number of elements that contribute to this. First, it reaches a particular period when the child’s growth rate in both weight and height remains stagnant or rather it appears to be very sluggish. This is very normal and should not worry about the parent at all.

Genetics also plays a big role when comparing a baby’s weight gain to its height. If any of the parents have a gene for dwarfism or slow growth in their family, then the child might end up gaining more weight than height in the first months after birth.

Sex also matters since boys mostly increase in weight and height faster than girls. Your doctor will know whether your child is increasing in weight and height normally by comparing your child’s weight and height with other children of the same sex and age as your child.

The baby weight gain chart shows that slow down in height and shoots up in weight can be quite alarming and medical assistance should be immediately sought. Measuring the circumference of your child’s head is also very paramount because it serves as an indication as to whether your child’s brain is growing.
