Baby size and baby weight

Baby weight at Lottili

For us at Lottili, baby weight is more important than baby size. We are often asked when the baby can sleep in the bassinet. Consequently, many people would also like to know at what age or weight this is no longer advisable. 

In our spring cribs, babies find a safe place to sleep even as newborns. This is because the spring cradles are designed for a baby weight of 3 kg or more, so for most children this applies from birth. What’s more, the earlier you use the hammock, the better. It is the best place for your baby to get a restful sleep so that he or she can calm down quickly.

Basically, the upper limit for our spring cradles is a maximum weight of 12 kg, but it is extremely unlikely that your child will actually sleep in it for that long. As soon as babies turn over on their own, they should no longer sleep in the bassinet. Most children can do this by the age of 8 months. This means, as you can see from the tables, that this point is usually reached much earlier, before the baby weighs 12 kg.

A boy at 8 months weighs on average around 8,600 g (according to RKI 8,800 g), while a girl at that age weighs around 7,900 g (according to RKI 8,100 g). Children aged 8 months can almost all turn around independently.

Baby size and baby weight at birth

Basically, baby weight is not just an integral part of every birth greeting card or email. In fact, baby weight and baby size are important factors from which doctors and midwives can determine a lot. Even during pregnancy, you regularly check how big and how heavy your baby is.

Babies grow extremely quickly in the first few months of life. This means that a newborn gains around 150 grams of weight per week. After the first birthday, growth and weight gain slow down.  

The weight of newborns

According to studies by the World Health Organization (WHO), the weight of newborns is between 3,300 and 3,500 grams. A baby weight between 2,800 and 4,200 grams is also considered normal. After birth, your baby will initially lose weight. Thereafter there is a steady increase. Fluctuations are completely natural and depend on a wide variety of factors.

So don't let yourself go crazy: every baby develops individually and at their own pace.

A rule of thumb:
Within the first six months, your baby's birth weight doubles, while your baby's weight triples by the first birthday.

Weight tables and percentile curves help doctors and you to achieve healthy weight and keep an eye on your child’s individual development.

Baby weight, baby height and percentiles

The term percentile is often mentioned in connection with baby weight and size. These values ​​are the benchmark for statistical variables in the health check. Better said, the percentile curve shows whether your baby is developing healthily, even if his weight and height deviate from the norm. Even if your child sets a completely different pace than the average, the percentile curve shows whether the values ​​are within the statistical spread.

The examining doctor creates the percentile curve during regular examinations. To do this, it measures the current values ​​(baby weight and baby size) and determines whether your child is developing normally. Ideally, the curve points consistently upwards.

Statistical data for baby weight and baby height

According to data from the Robert Koch Institute (RKI), the following average values ​​​​are found for your baby's weight. All data comes from the RKI and is clearly presented here for you.

What does the percentile curve mean?

The WHO also provides the best visual aids. The following graphs are from the World Health Organization and are intended as reference values ​​for baby weight between 0 and 2 years of age.

First: First of all, you will find the 50th percentile in the middle in green. It represents the average values. All values ​​that are within the two outer curves are still considered acceptable.
Second: If your baby's values ​​are in the lower 3rd percentile, that means that only 3% of children of the same age are lighter. The majority are then heavier. However, if your child's values ​​​​are at the 97th percentile, then the opposite is true: 97% of all children of the same age would then be lighter. 

Constant monitoring of the baby's weight and size is particularly important in the first two years of life. It ensures that your baby develops healthily. If the values ​​deviate significantly from the curve, experts can also draw conclusions that may indicate nutritional deficiencies or growth problems.  

Every child is different

So don't be alarmed or unsettled if your baby's performance is not average. Experience has shown that light children simply catch up with a growth spurt at some point, sooner or later. If your child is heavier than the rest, they will work off the baby fat when they start crawling or walking. Therefore, this is no reason to worry either. Your doctors will let you know if there is anything really wrong. This means that everything else varies from person to person.
