Are you an expectant mother? So maybe you know the situation when you visit the doctor just before your planned birth, he says you your little baby is growing as was expected and is almost ready to came into the world. And the weight is also normal, the doctor says. But what does it mean, normal? Do you know that? Let’s read about babies’ birth weight.
If you’re an expectant mother, we are sure you think about the birth a lot of time and these considerations must be connected with the birth weight of your baby too. Actually, the doctors distinguish a few categories of babies’ birth weight. Here they are:
The weight under the limit – less than 2500 g.
The normal weight (physiological) – 2500 – 4000 g.
The weight above the limit – more than 4000 g.
The macrosomia – more than 5000 g.
The weight under the limit
The weight under the limit can have a many reasons. Very often it’s because your baby is premature or preterm (it means he is born before 37 weeks). Thanks to a modern medicine we know a lot about the preterm babies but there are still some moments which we cannot explain.
For example, we know about some kind of risk factors for the mothers but we are still not able to name all of them. Here are some factors which can increase the chance for preterm birth:
– Extreme obesity or extreme malnutrition
– Bad prenatal care
– Drinking alcohol or using drugs
– Bad health conditions (diabetes, some kind of infection etc.)
– Expecting twins or multiples
– Being pregnant very soon after the previous birth
Now you know some risk factors for preterm birth. But how do you find the birth is coming sooner that was expected? Here are the symptoms of preterm birth: a backache (in lower back), a contraction (every 10 minutes or less), a cramping, flu symptoms (the nausea, vomiting or diarrhea), a vaginal discharge or a vaginal bleeding. If you have more symptoms from the list, call the doctor asap.

Amillia weighed 10 oz (283 g) – USA, born at 21 weeks
Marian birth weight 10 oz (283 g) – UK at 34 weeks
The normal weight
As we wrote above, the normal weight is between 2500 and 4000 g (the average is around 3300 g). If we say the weight is between the first number and the second one, we mean the weight just after the birth. A few hours after the birth your baby loose about 5 % of his weight. It’s because he’s just losing fluid. It’s normal, don’t be afraid, within next 14 days he will be back up to his birth weight.
The weight above the limit and the macrosomia
About 10 percent (in Europe more) of all babies weigh more than 4000 g and very rarely they have more than 4500 g. If they have more than is written, we say they have a fetal macrosomia and they must be bringing into the world via Caesarean section (very often but not always).
Maybe you are asking yourself just know why some mothers have bigger babies than the different one. Specialist say there are many reasons for that. The influence can have the race, the economic status of the parents and also the environment where the parents live.
But very important (maybe the most important) are the hereditary characteristics and so if are the parents tall, more likely they will have a big baby. Unfortunately, nothing from this list of the reasons can make sure for 100 % that your baby will be bigger than others.
