Baby’s Height and Weight Chart

A baby’s weight and height becomes a general matter of concern for every parent over time. Some babies have exponential growth soon after their birth, while some undergo a tedious process of acquiring the right weight and height after a certain age. Hence, it is highly essential to keep a track of a newborn baby weight in order to understand if the baby’s body mass index is headed in the right direction.

To know whether your baby is fairing with the body mass index ratio at a certain age, a chart should be strictly maintained to monitor the developmental rate. However, the average length of a newborn baby is around 50 cms and increases to 75 cms in the first year. Maintaining a growth chart helps parents and pediatricians access the nourishment status of a baby. Be it a baby boy or a baby girl, caring for the little one becomes easy once you know what’s their weight and height. A baby boy’s weight soon after birth aggregates to 2.6 kgs while the height totals to 47.1 cm. When it comes to a baby’s girl weight chart, the weight totals to 2.6 kgs and the height to 46.7 cms.

Caring for the little one becomes extremely crucial in their wee ages of development. Therefore, to maintain a proper nutrition, parents must prepare a monthly chart to track the month wise transition. So, let’s look at the month-wise progress of an ideal new born till the age of 1 year.

Although, the height and weight of a baby girl and boy ranges the same at the time of birth, the difference becomes apparent in time. Yes, that’s true as baby boys are slightly taller and heavier than baby girls and this is why there are variations in their growth patterns.

How Does Breastfeeding Affect Weight

Normally breastfed babies gain weight more rapidly than formula-fed peers during their first 2-3 months of birth. Breastfeeding does not often lead to obesity but in some cases where newborns gain weight during infancy, they may readily lose weight once they become mobile. What’s important to note here is that breastmilk is the perfect and most-healthiest form of food. Try feeding your baby breastmilk as long as possible as it provides the perfect nutrients and fats for appropriate growth and brain development. The total amount of calories or fats present in breastmilk is not affected by mother’s dietary fat and therefore, it is the safest to feed the baby at the time of their birth.

Infant Growth Spurts

While we know that growth spurts happen anytime during the first year of birth, your little bundle of happiness will mostly show the initial signs of spurt between 1 and 3 weeks, and another between 6 and 8 weeks. Post this stage, your baby will grow in intervals of 3 months, 6 months and 9 months respectively. Usually a baby’s growth spurt lasts only for a couple of days. But in order to recognize your little one’s spurt, here’s what you need to know:

  • Baby clamors for more and more food

  • Baby will appear crankier than usual

  • Baby will be awake more often at night

It is especially during this stage when your little one’s appetite goes oh-give-me-more-food, breastfed milk should be provided more frequently. It is your baby’s way of boosting your milk supply to rally against his massive growing appetite. In case, this gets you worried about weight gain, keep an eye on diapers and his weight trajectory. If the baby is gaining ounces by the day and is soaking more than five diapers a day, be assured it’s doing just fine. It will only last till his hunger pangs come to a cease and growth spurt sees the last light of the day.

Therefore, for a baby to grow healthy, breastmilk is what mothers need to feed the baby for the first six months. It contains an ideal mix of nutrients apt for the baby’s growth. Since infants can’t prepare their own food, they depend on parents to prepare or feed them food that will promote their health, boosting their weight and height as they grow.
