At 4 months pregnant (around 16-20 weeks), the baby is small enough to move freely and change positions often, often lying sideways (transverse) or in various orientations as there's plenty of space; the key is constant movement, not a fixed position, with the head-down (cephalic) position becoming more important much later, closer to birth.
Your baby's facial features have formed and so have their eyelashes and eyelids. Your little one can squint, make faces, and suck their tiny thumb, which now has nails like their other digits. The nervous system is running, and the genitalia is fully formed.
Contrary to popular belief, the baby isn't always positioned on the right or left side of the womb. In fact, during most of the pregnancy, the baby is centrally positioned in the midline pelvic region within the uterus.
The baby's ears have moved into their final position on the sides of the head. The baby's arms and legs grow longer, and their fingers and toes are no longer webbed. Fine hair, known as lanugo, begins to cover the baby's body, helping to regulate the body temperature.
Place your hands on the lower part of her abdomen, with your fingers gently pressing inwards just above the pubic bone. You may feel the hard round head there. If the part feels softer and irregular, it is likely the baby's bottom or feet; a breech presentation.
First: Put both your hands flat on the mother's belly and feel the top of the uterus with the palms and fingers of both hands. Most often you will feel the baby's bottom here. You will feel soft irregular shapes that don't move easily under gentle pressure from your hands. You may be able to feel his legs nearby.
Common symptoms may include round ligament pain, sensitive gums, nasal congestion, and stretch marks. Food cravings and vivid dreams are also common. Your baby is growing fast, now about 5 inches long and beginning to make fists, swallow amniotic fluid, and even hear sounds.
The best sleeping position during pregnancy is on your side. The left side is especially good because it lets the most blood flow to the baby. It also improves your kidney function. One choice is to place a pillow between your knees and one under your belly (abdomen).
Pregnant women should also try to avoid all marinated foods, pickled goods, processed foods, foods that are high in monosodium glutamate, as well as caffeinated drinks like tea, coffee and carbonated drinks as these all contain substances which could have adverse effects on the health of your unborn child.
The fetus is inside the membrane sac within the uterus and high within the abdomen. The muscles of your abdomen support much of its weight.
Cravings can occur at any point during your pregnancy. If you're going to have cravings, it's common for them to start in the first trimester around the fifth week. It is even possible you get cravings at 1-week pregnant!
Ramzi theory
If your placenta is forming on the right side, you're having a boy, and if it's developing on the left side, you're having a girl. Experts don't consider the Ramzi method to be a reliable way of predicting your baby's sex.
Most women don't feel their baby move until month 5 (weeks 17-20) or month 6 (weeks 21-24). You may feel it as early as week 14 and as late as week 26. At first, your baby's movements may feel like nothing more than a very gentle flutter. Some women don't even realize that what they're feeling is their moving baby.
Weeks 16-18 means that you have started your fourth month of pregnancy. During these weeks, you can expect your baby to be able to move their eyes, develop toenails and hear sounds.
There's no single "hardest" month, as challenges vary, but many find the first trimester tough due to nausea, fatigue, and hormonal shifts, while the third trimester (months 7-9) often brings the most physical discomfort from the baby's size, affecting sleep, mobility, and causing aches, heartburn, and frequent urination. The difficulty often shifts as pregnancy progresses, with the first months focused on adjustment and the later months on physical strain and preparation for birth.
How can I take good care of myself during pregnancy?
Prenatal sleep
At first, we need to clarify one thing: it's a known fact that babies sleep in their mother's womb. They usually sleep when their mothers are going about their everyday chores. It's almost as though the mother's daily routine would seem to reassure the fetus, which sleeps until mom goes to bed at night.
Movement and physical development milestones at 4 months
They can hold their head up without support. Might be able to roll over onto their back. Will push down on their legs when their feet are on a hard surface. Can shake a toy they're holding.
Other common symptoms you can experience during the 4th month of pregnancy are round ligament pain, varicose veins, stretch marks, backache, nose bleed, and haemorrhoids. No matter how many symptoms you face, it will all be worth enough when you hold your little ones in your hand!
Five key warning signs during pregnancy needing immediate medical attention include vaginal bleeding, severe headaches with vision changes, decreased baby movement, severe abdominal pain/cramping, and signs of preterm labor like regular contractions or fluid leakage, as these can signal serious issues like miscarriage, preeclampsia, placental problems, or infection. Always contact your healthcare provider or seek emergency care for these symptoms.
Those initial movements might feel like small flutters or gentle tumbles, and initially, they may be hard to register. Sometimes, it can be difficult to discern your baby's movements from gas but remember: gas passes. If you feel continued movement, that's probably your baby giving a little "hello."
When you'll feel your baby move. You should start to feel your baby move between 16 to 24 weeks of pregnancy. If this is your first baby, you might not feel movements until after 20 weeks. If you have not felt your baby move by 24 weeks, tell your midwife.
