Baby weight chart by month in kg

As new parents, it is very natural to worry about whether your child is developing well. One of the most common questions that new mothers often ask is "Is my baby gaining weight properly?" To avoid too much worry and have criteria to monitor your child's development, the baby weight chart by month in kg can provide a useful guide to track your child's growth that you need. In this article, Snuggle Cubs will explore everything you need to know about newborn weight, the factors that affect it, and how to track it each month..

What is the average baby weight by month?

The weight of each newborn baby in the first year of life shows a clear increase, fastest during the early months after birth. Newborns typically double their weight by 5 months and triple it by 1 year, which is easier to recognize. However, understanding the normal weight gain or loss in children will help you feel more confident and less confused.

Normal weight of newborn baby in kg

At birth, a baby's weight can vary depending on several factors such as genetics and birth circumstances. The average weight of a newborn baby is about 2.5 kg to 4.0 kg at birth.

However, this number may vary. The most important thing is that your baby is gradually gaining weight after birth. Sometimes it's normal for a baby to lose a little weight in the first few days after birth, but then the baby will start to gain weight again right away.

Weight of average 6 month old

When they are six months old, babies typically gain between 0.9 kg and 1.1 kg per month. On average, a six-month-old baby weighs between 7.3 kg and 8.9 kg. However, some children may weigh slightly less or more, which is completely normal. The most important thing is that the child's growth model ensures nutrition and balance.

1 year old baby weight in kg

By the time they are 12 months old (1 year), most babies will weigh between 9 to 11 kg. Typically, after the age of 1, a child's weight gain will slow down compared to the 6-month stage. The weight of children varies due to factors related to feeding methods, birth conditions, and some genetic factors.

However, parents do not need to worry too much if their children weigh 1-2 kg less than their peers of the same age. Instead, focus on a proper diet and lifestyle for the child.

What affects baby weight?

In addition to understanding the baby weight chart by month in kg, understanding the factors that affect a child's weight is also the foundation for parents to best prepare for their child's healthy development. Genetic factors, birth conditions, and many other factors also have a significant impact:

Fixed factors (before birth):

• Genetics: The height and weight of both the father and mother have a significant impact on the child's weight.

• Maternal Age: Women in their teenage years and over 35 years old have a higher risk of giving birth to low birth weight babies.

• Number of babies: Twins or triplets are usually lighter than single-born children. The firstborn tends to be lighter than the second child.

• Gestation period: Premature babies will weigh less because they have not fully developed in the womb.

• Gender: Boys usually weigh a little more than girls. However, in some special cases, this may vary when comparing between one family and another.

Modifiable factors ( During and after pregnancy):

• Nutrition: Ensure that the baby receives adequate nutrition through breast milk or formula, and introduce solid foods at the right time (around 6 months old).

• Maternal health: Poor diet, habits like smoking, drinking alcohol, or conditions such as diabetes and high blood pressure during pregnancy can negatively affect the child's weight.

• Sleep health: Deep sleep is very important for development, as growth hormone is released strongly during this time.

• Physical activity: As the child grows and begins to move more (rolling, crawling, creeping), the rate of weight gain may slow down. This is a positive sign of healthy development.

• Medical conditions: Certain issues, such as reflux or food allergies can hinder the absorption of nutrients in children. If you have concerns, always consult a healthcare professional for personalized advice.

Baby Weight and Height: What’s Normal?

Growth isn’t just about weight. Height is just as crucial when assessing your baby’s development. A baby might have an average weight but be taller or shorter than average and vice versa. Monitoring both weight and height is essential to ensure your baby is developing normally. A well-proportional baby will have both their weight and height following a similar growth pattern.

It’s important to remember that babies in spurts and while weight is a critical factor in assessing growth, height is equally important. Both are part of a child’s overall health. Here’s example of a combined chart of baby weight and height chart by age:

Tips of measuring your baby’s weight and height at home

To monitor your child's development right at home is not difficult at all. Here are a few small tips to help you measure your baby's weight and height accurately and professionally:

• For weight: Always you can use a specialized baby scale. These scale are designed to measure your baby’s weight safely, with greater accuracy than a standard bathroom scale.

• For height: You should place the baby on their back on a firm surface. Use a soft measuring tape or a height chart (already attached to the wall) to measure from the top of the head to the heel of the child. Make sure the baby lies flat and stretches their legs completely for the most accurate measurements.

What to expect?

The journey of caring for and monitoring the physical development of children is one of the top concerns of parents. Below are important notes and milestones you need to know:

The stage from 4 to 6 months old:

• 4 months baby weight in kg: The average weight of the baby at this time is about 6.0-6.4 kg.

• The weight of a 5-month-old baby: The baby can reach a milestone of 6.4-6.8 kg.

• The weight of a 6-month-old baby: The average weight is about 7.0-7.3 kg. This is also the time when the baby starts to get acquainted with solid food.

The stage after 1 year old:

• The weight of a 1-year-old baby: The average weight of a baby is about 9-11 kg.

• Weight chart for boys (12 to 24 months): After the first birthday, the weight gain rate of the baby will slow down. From 12 to 24 months old, the weight of boys usually increases by about 2-3 kg.

Percentile calculator age height weight

In monitoring the development of infants, percentiles are a crucial indicator that helps doctors assess how baby is growing compared to a peer group of the same age and gender. Specially:  

• 50th percentile: The babies have weight, height, or head circumference that is average compared to their peers of the same age and gender.

• 75th percentile: The babies who weigh or are taller than 75% of children of the same age and gender.

• 25th percentile: The babies who weigh or are taller than 25% of children of the same age and gender.

Parents should monitor the changes in percentiles over time, rather than just focusing on a single measurement. Significant changes in percentiles may be a sign of a health issue that needs further examination.

How to calculate percentile

To determine your baby’s percentile, you will need the following information:

• Age and gender: The gender and age of children affect their level of development.

• Weight, height, and head circumference: These measurements are compared to standard growth charts to determine percentile.

Online tools like Guava health and inch calculator allow you to input your baby’s data to calculate their percentile.

When to Be Concerned & Talk to a Doctor

While babies typically grow at their own pace, there are times when parents should pay close attention and seek timely advice.

• Sudden weight loss or a failure to gain weight can be a sign of a health problem. Please consult a doctor if this occurs.

• Excessive weight gain, sometimes it signals underlying issues such as overfeeding, which can lead to other complications.

Signs to recognize if a child is underweight or overweight:

• Underweight: Slow weight gain, achieving developmental milestones lower than expected.

• Overweight: Excessive weight gain, especially if this causes physical discomfort for the baby.

Additionally, trust your parental instincts. If you or a family member notice any signs of abnormal development, new parents should monitor the situation closely and take the baby to see a doctor when necessary.
