In a review she published in the journal European Cells and Materials , Nowlan described how a lack of fetal movement can lead to a variety of congenital disorders, such as shortened joints and thin bones that are susceptible to fracture.
For pregnant women wondering if their baby is too kicky, or not kicky enough, Nowlan said there's no established amount of normal fetal movement during pregnancy. That's because it's difficult for scientists to study fetal movements, because the only way to measure them is in the hospital and it can be done for only a short period at a time.
To get around this problem, Nowlan and her colleagues are working on developing a fetal-movement monitor that the mother can wear during her normal daily activities. The researchers tested the monitor on 44 women who were 24 to 34 weeks pregnant and could accurately detect breathing, startle movements and other general body movements. One study, published in in the journal Human Fetal and Neonatal Movement Patterns , found that boys may move around more in the womb than girls.
The average number of leg movements was much higher in the boys compared to the girls at 20, 34 and 37 weeks, that study found. But the study's sample size was small, only 37 babies, so Nowlan and her colleagues are hesitant to claim there's a relationship between gender and fetal movement. In her own two pregnancies, for example, she said she was much more sensitive to the movements of her second child compared to those of her first. She hypothesized that this variation could have arisen because the womb muscles are more stretched out after the first pregnancy, a topic she's now studying.
The most-pronounced movements mothers will feel are the baby's kicks. The first is that it gives muscles and limbs exercise. It also shows response to stimuli and, as the current study suggests, helps the brain make connections for spatial sense. Many fetuses have longer than usual periods of inactivity.
In some cases of stillborn infants or in utero death, they can come as a result of decreased movement. Still, the medical community is not sure based on those perceptions which babies may be more at risk than others, Samuel said.
Researchers found that fetal kicks in the third trimester may help the infant develop brain areas linked to sensory input. The singer revealed she had an emergency cesarean delivery for her twins. Having preeclampsia in a first pregnancy increases your risk of developing it again in a second pregnancy. Your degree of risk depends on the severity…. A new study finds that epidurals do not affect child development in their later years.
A fetal arrhythmia is an irregular heart rate — too fast, too slow, or otherwise outside the norm. It's often benign. Postpartum diarrhea after a C-section is normal.

Additionally, if you stop feeling any movement from the fetus, you should reach out. Otherwise, activity levels vary. If you have additional questions, please reach out to your TopLine MD provider for more information.
However, there are several different reasons why you may feel your child move in the womb, such as the following: Babies require exercise, even while in the womb, to promote healthy joint and bone development. Your baby may just be performing natural, healthy movements.
As the child grows, it begins to become more active, so you may start to feel like your baby is kicking too much or more than usual. Factors that may impact how you experience fetal movement include, but are not limited to: The placement of the placenta : At times, the placenta can be at the front of the uterus and create a pillow-like effect, keeping the mother from feeling the movement of the baby as intensely.
This means that while the baby may be moving within the uterus, the mother has a more difficult time feeling it. Weight of the mother: Patients who are overweight often have a more difficult time feeling the movement of the baby, as they have a bit of extra padding to hide those movements. The personality of the baby: Some babies are more active than others. When Should You Worry? Facebook Twitter LinkedIn Email. Related Posts. September 2nd, August 20th,
