Research shows girls kick as often as boys. Babies who kick a lot in the womb are also more active after birth. Some mothers have more trouble feeling the kicks than others. If the placenta is on the front side of the womb, or if you are overweight, you will feel the kicks less.
Conclusion: Despite numerous prior studies derived from small samples failing to reveal significant sex differences in fetal activity, the present study demonstrates that males are about 10% more active than females during the latter two-thirds of pregnancy and are even more so following birth.
A number of ultrasound and animal studies have shown that the fetus has a circadian pattern that involves increased movement in the evening, and this is likely to reflect normal development.”
Most of the pregnant woman observe more movement during night time. This can be due to your baby becoming more alert during the night when he or she is not feeling any activity. During the day time, pregnant women are more active because of which the baby may go into its sleeping mode.
The baby's movements are felt stronger on the side the placenta has attached itself to the womb. As mentioned above, if the placenta is attached to the right side and you feel more movement on the right side, you could be carrying a boy.
No, your baby's movements can't predict if you're going to have a boy or a girl. You may have heard people say that if your baby isn't very active in the womb, then you're likely to be having a girl.
32 weeks to 35 weeks
This may be the most exciting time for feeling your baby move, as at 32 weeks your baby's movements will be at their peak. Afterwards, the frequency of your baby's movements will stay roughly the same until you go into labour (Jakes et al 2018, RCOG 2011, 2019).
Early in your pregnancy, you may just feel a few flutters every now and then. But as your baby grows -- usually by the end of the second trimester -- the kicks should grow stronger and more frequent. Studies show that by the third trimester, the baby moves about 30 times each hour.
Your baby may just be performing natural, healthy movements. You've recently eaten. Babies are most active after you've eaten a meal, and with a full stomach, mothers are more likely to feel the movements of the baby, as there is less overall room for the baby to move.
Yup, your baby on board can feel — and respond — when you stroke your tummy.
Women are more likely to move and to move over longer distances at the start of co-residence than men.
Biological differences between the sexes are apparent even from the early part of the pregnancy. The crown-rump length is larger in male fetuses compared to females in the first trimester. Placentae of male and female fetuses have different protein and gene expressions, especially in adverse conditions.
Just like newborns, fetuses spend most of their time sleeping. Indeed, throughout much of the pregnancy, your baby sleeps 90 to 95% of the day. Some of these hours are spent in deep sleep, some in REM sleep, and some in an indeterminate state—a result of their immature brain.

Head-down babies will kick more strongly on one side and towards the top of the bump. Later on, some babies with their head at the bottom like to stretch their legs every so often and this can feel like something is sticking out on both sides of your bump - one side will be the bottom, the other side will be the feet.
Later, as your baby gets larger, you'll feel more stretches and rolls, and fewer kicks and punches. As your uterus gets more crowded, you may feel your baby move less. If you think your baby is less active than usual, do a “kick count.” Keep track of the number of movements in one hour.
A recent study suggests that carrying a male or female foetus could lead to different immune responses in pregnant women. Pregnant women carrying girls have a greater chance of experiencing nausea and fatigue, according to the results of a study from the USA's Ohio State University Wexner Medical Center.
It's all about Dad's genes
A man's X and a woman's X combine to become a girl, and a man's Y combines with a woman's X to become a boy. But if the sperm don't have equal Xs and Ys, or if other genetic factors are at play, it can affect the sex ratio.
The two sex chromosomes in the egg and sperm are what determine whether you'll have a boy or girl. Eggs always have an X chromosome, and sperm have either an X or Y chromosome. Whichever sperm is the winner will penetrate and fertilize the egg, creating either an XX (girl) or XY (boy) pair.
If it's forming on the left side, it's probably a girl. There's no evidence that it works, and mainstream experts dismiss it. Some expecting moms like to try it anyway, just for kicks. But the chances of this technique correctly predicting your baby's sex is about 50/50 – no better than guessing.
Fetal movements typically increase when the mother is hungry, reflecting lowered blood sugar levels in the mother and fetus. This is similar to the increased activity of most animals when they are seeking food, followed by a period of quietness when they are fed.
