Several factors contribute to high birth weight, including certain health conditions and family history, Simhan said. Diabetes, or gestational diabetes — which develops during pregnancy — may predispose women to having babies over 10 pounds, he said.
A: A baby who weighs more than 8 pounds 13 ounces at the time of birth is considered a “macrosomal” or “large for gestational age” baby. There are certainly women around the world who can deliver these larger babies vaginally.
Although the average birth weight is 7 pounds and 11 ounces, and more than 10 pounds is considered quite large, “there is quite a wide range as to what is the right size for any mother or baby” , according to Dr. Hyagriv Simhan, Director of Maternal-Fetal Medicine at Magee-Women’s Hospital at the University of Pittsburgh Medical Center, USA…
Historically, babies with macrosomia have weighed more than 4,000 grams (8 pounds, 13 ounces) or more than 4,500 grams (9 pounds, 15 ounces) at birth. Macrosome babies are more likely to have a difficult birth. But the risk of complications is significantly greater when a baby is born weighing more than 4,500 grams.
Large babies can be born through a normal, vaginal delivery – but it’s best to give birth where you can access specialized medical services, just in case things don’t go according to plan. Every pregnancy and birth is unique, so talk to your doctor or midwife about the best place to give birth.
Vaginal birth for a big baby
Many parents give birth to babies weighing over 4.5 kg without complications or permanent injuries. Vaginal delivery is associated with fewer complications for both parents and baby, and reduces the likelihood of complications in future pregnancies.
According to Guinness World Records, the heaviest baby ever was born in 1955 in Aversa, Italy. This little boy weighed 22 pounds and 8 ounces. Guinness World Records reports that the heaviest baby born in the United States was 22 pounds in Seville, Ohio in 1879.
Genetic factors and maternal conditions such as obesity or diabetes can cause fetal macrosomia. Rarely does a baby have an illness that makes it grow faster and bigger. Sometimes it is unknown what causes a baby to be taller than average.
Current NICE guidelines on labor induction recommend only offering labor induction at 41 or 42 weeks for otherwise healthy women who are having a baby larger than average. This analysis suggests that earlier initiation is likely safe and may be an option women should consider.
How big are newborns? Newborns come in a variety of healthy sizes. Most babies born between 37 and 40 weeks weigh between 5 pounds, 8 ounces (2,500 grams) and 8 pounds, 13 ounces (4,000 grams). Newborns who are lighter or heavier than the average baby are usually fine.
Interestingly, mothers of larger babies report that the second stage of labor is usually much easier than with previous babies who were smaller. Some midwives say this is because the woman’s muscles are better able to grip a larger baby to help push him out.
Abigail Corbin, a midwife in Milton, Ontario, understands why some expectant mothers panic. “The trend is the bigger the baby, the more difficult it is to deliver,” she says, “but that’s actually just one factor of many that influence the course of labor.” p>
We also know that a baby’s length is related to their eventual height and weight. In other words, heavy babies tend to get fat and tall babies tend to get tall. Studies have also shown that bigger parents make bigger babies, which in turn make bigger adults
The Guinness World Record for heaviest baby to survive infancy belongs to a boy weighing 22 pounds, 8 ounces who was born in 1955 in Aversa, Italy. In 2019, a New Yorker named Joy Buckley gave birth to a daughter who weighed 15 pounds, 5 ounces.
If your bump is larger than you expect for how wide you should be, then you may be carrying a large baby. Gut feeling: The doctor or midwife will run their hands over your stomach to feel for the size and position of the baby.
Here’s what you need to know about extra large babies. Birth weight has been trending upwards in the US for decades, with the average newborn weight now standing at a healthy 7.5 pounds. Beyond this gentle statistical increase, however, there are troubling outliers. About 1 percent of babies weigh more than 9 pounds.
