In Month 4, your baby is
the size of an Avocado
In Month 4 of pregnancy, your baby is growing rapidly! Expect more energy, visible baby bump, and exciting developments as your pregnancy journey continues.
Welcome to the beginning of your second trimester - the fourth month of pregnancy! This month is often referred to as the "honeymoon period" of pregnancy. Many women find this stage more enjoyable as early pregnancy symptoms like nausea and fatigue often ease up. At the same time, your baby is growing rapidly, and you might even begin to notice the first hints of a baby bump.
Your baby is growing rapidly this month, with exciting developments in size, features, and movement. Here's what’s happening week by week:
Your baby's head is now proportionally large compared to the rest of their body. Soon your baby might start sucking their thumb, a key reflex that develops during this time. Inside the umbilical cord, your baby's intestines are continuing to grow but will soon move into their abdomen as the space inside develops. Meanwhile, the placenta is gradually growing to provide essential support for your baby.
Your baby is about 8 cm long and weighs around 45 g. He or she is roughly the size of a kiwi fruit. The baby's body is growing faster than the head, bringing it into the right proportions, the neck has developed, and the arms are nearly their final length.
In the 15th week of pregnancy, your baby is developing finely detailed features, like eyebrows and hair, and their skeleton is beginning to harden. By now, the ears are formed properly on the sides of the head and the eyes are moving from the side of the head to the front of the face. Your active baby is moving constantly, though you can't feel it yet.
Your baby's legs are more developed, their head is more upright, and their ears are close to their final position. Hair is still starting to grow, although isn't visible yet. Your baby is the size of an avocado.
Your baby is growing steadily, and each week brings new milestones. Let’s take a closer look at the incredible changes happening in your womb during this month.
During the fourth month, your baby's organs continue to develop and mature. The nervous system is becoming more complex, with the brain and spinal cord undergoing rapid growth. The baby's lungs are forming tiny air sacs called alveoli, which will eventually allow them to breathe independently after birth. The digestive system is also developing, with the intestines continuing to grow and the liver beginning to produce bile.
By the end of the fourth month, your baby's facial features are becoming more distinct. The eyes, nose, and mouth are visible, and the baby can even make facial expressions like squinting and frowning. The baby's ears have moved into their final position on the sides of the head, and the neck is becoming more defined. The baby's arms and legs are growing 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 their body temperature.
At the end of the fourth month, your baby typically weighs between 110 to 140 grams and measures approximately 10 to 13 centimetres from crown to rump. This rapid growth is supported by the nutrients you provide through your diet and the placenta, which is now fully developed and functioning efficiently. You can track your baby bump's growth using pregnancy weight gain calculators.
While you may not feel it just yet, your baby is starting to move! They’re practising stretching, flexing, and even hiccuping. By the end of the fourth month, you might feel the first faint flutters, often called “quickening.”
At 4 months, your baby is growing stronger every day. Keep nurturing yourself—you're building the foundation for a bright future together!
This month, your body is adapting to support your growing baby. Here’s what you might experience:
Baby Bump
Your uterus is expanding, and you may notice a small bump appearing.
Increased Energy
Many women feel more energetic this month as nausea and fatigue subside.
Breast Changes
Your breasts may feel fuller, and the areolas may darken as your body prepares for breastfeeding.
Skin Changes
You might notice a pregnancy glow due to increased blood flow or darker patches of skin (melasma) caused by hormones.

By now, your appetite may have returned, and you might feel hungrier than before. Focus on balanced, nutritious meals to support your baby’s growth and your own health.
Staying active during this month is a great way to improve circulation, reduce stress, and prepare your body for labour.
Regular prenatal check-ups are essential during this month to ensure your baby is growing well and you’re staying healthy.
Common Check-Ups
Ultrasound
If you haven’t had one yet, this month might include an ultrasound. This scan checks your baby’s growth and may even give you a chance to find out the baby’s gender if you wish.
Mental Health
In the 4th month of pregnancy, many women feel relief as early symptoms like nausea and fatigue subside, but emotional ups and downs may still occur due to hormonal changes. Focus on self-care by staying connected with loved ones, exercising gently, eating well, and getting enough rest. Engaging in enjoyable activities or prenatal classes can help improve your mood. If you continue to feel overwhelmed, consult your doctor for support.
The reduction in early pregnancy symptoms like nausea and fatigue often brings a renewed sense of energy.
No sleeping on your back is not recommended for pregnant women. It’s best to start sleeping on your side to improve circulation, especially after week 20.
While normal discharge is harmless, a sudden increase in watery discharge or discharge mixed with blood could indicate amniotic fluid leakage or other concerns. If this happens, seek medical attention immediately.
Nasal congestion, often called "pregnancy rhinitis," is common due to increased blood flow and hormonal changes. Using a saline spray or humidifier can help relieve discomfort.
Yes, the fourth month is a great time to start prenatal yoga if your doctor approves. It helps improve flexibility, reduce stress, and prepare your body for childbirth. Just ensure you're practising under a qualified instructor and avoiding poses that put pressure on your abdomen.
