PREGNANCY WEEK 35: BABY DEVELOPMENT MOVEMENT AND BODY CHANGES

Pregnancy Week 35 brings you even closer to meeting your baby. Your baby continues gaining weight and body fat while the brain, lungs and nervous system continue to mature.

At this stage, your baby's movements may feel strong and familiar. Because your baby is growing and there is less space inside the uterus, the movements may feel different from earlier weeks, but your baby's usual pattern should remain noticeable.

For you, the final weeks can bring increased tiredness, heartburn, back discomfort, pelvic pressure, frequent urination and difficulty sleeping. Continuing prenatal care and preparing for birth can help you feel more organized as the due date approaches.

What Happens During Pregnancy Week 35?

During Week 35, your baby continues to gain weight and develop body fat.

The brain continues developing rapidly, and the nervous system becomes increasingly mature.

The lungs continue maturing in preparation for breathing after birth.

Your baby's muscles are becoming stronger, and the bones continue developing.

Your baby is also becoming better able to respond to sounds and other sensory experiences.

How Big Is the Baby at Week 35?

Your baby is approximately the size of a honeydew melon, although exact measurements vary.

Your baby will continue gaining weight during the final weeks of pregnancy.

The increasing amount of body fat gives your baby's body a fuller appearance and will help with temperature regulation after birth.

Baby's Movement at Week 35

Your baby's movements may now feel quite strong.

You may notice:

  • Kicks
  • Punches
  • Stretching
  • Turning
  • Rolling
  • Shifting
  • Hiccups
  • Rhythmic movements

Because your baby is larger, there is less room for large movements.

You may therefore notice more pushing, stretching and kicking rather than the bigger rolls you felt earlier in pregnancy.

Understanding Your Baby's Movement Pattern

By Week 35, you may recognize when your baby is usually active and when your baby tends to rest.

Every baby has an individual movement pattern.

There is no single number of movements that is considered normal for every pregnancy.

The important thing is knowing what is normal for your baby.

If you notice a significant reduction or clear change in your baby's usual movements, contact your maternity care provider promptly.

Baby's Brain Development

Your baby's brain continues developing rapidly.

The brain becomes increasingly complex, and connections between nerve cells continue forming.

These changes support movement, sensory processing and coordination.

Brain development continues throughout pregnancy and after birth.

Baby's Hearing

Your baby's hearing continues to mature.

Your baby can hear sounds from inside your body, including your heartbeat and breathing.

External sounds can also reach your baby.

Talking, reading or singing to your baby can be an enjoyable way to bond before birth.

Baby's Eyes

Your baby's eyes continue developing.

The eyelids can open and close, and the structures involved in vision continue maturing.

Your baby may respond to changes in light, although vision remains immature before birth.

Baby's Lungs

The lungs continue maturing during Week 35.

The respiratory system is becoming increasingly prepared for life outside the uterus, but development is still continuing.

The remaining weeks of pregnancy provide additional time for lung maturation.

Baby's Skin and Body Fat

Your baby continues storing fat underneath the skin.

The skin becomes smoother and the body develops a fuller appearance.

Vernix caseosa may still cover parts of your baby's skin and provide protection from the surrounding amniotic fluid.

Pregnancy Symptoms During Week 35

You may experience:

  • Heartburn
  • Constipation
  • Bloating
  • Back pain
  • Pelvic pressure
  • Leg cramps
  • Increased tiredness
  • Difficulty sleeping
  • Frequent urination
  • Mild swelling
  • Breast tenderness
  • Increased vaginal discharge
  • Occasional headaches
  • Shortness of breath

Symptoms vary from one pregnancy to another.

Your Growing Belly

Your uterus continues expanding as your baby grows.

You may feel heavier and find activities such as bending, walking for long periods or getting comfortable in bed more difficult.

Pressure on your bladder can also make you urinate frequently.

Take regular breaks and allow yourself enough time to rest.

Back and Pelvic Discomfort

The growing uterus and changes in posture can place additional pressure on your lower back and pelvis.

To improve comfort:

  • Maintain good posture.
  • Avoid heavy lifting.
  • Wear comfortable supportive shoes.
  • Change positions regularly.
  • Use pillows while sleeping.
  • Take gentle walks if appropriate.
  • Practice pregnancy-safe stretching.

Talk to your healthcare provider if pain is severe, persistent or unusual.

Heartburn During Week 35

Heartburn may continue during the final weeks of pregnancy.

You may find it helpful to:

  • Eat smaller meals.
  • Eat slowly.
  • Avoid foods that trigger heartburn.

  • Avoid large meals close to bedtime.

Ask your healthcare provider before taking any medication for heartburn.

Constipation

Constipation can continue during the third trimester.

Helpful habits include:

  • Drinking enough water.

  • Eating fiber-rich foods.
  • Staying physically active if appropriate.

If constipation becomes severe or persistent, consult your healthcare provider.

Leg Cramps and Swelling

Leg cramps can occur during pregnancy.

Gentle stretching and regular movement may help.

Mild swelling of the feet and ankles can also occur.

However, sudden or significant swelling, especially when accompanied by severe headache, vision changes or upper abdominal pain, requires prompt medical assessment.

Breast Changes

Your breasts continue preparing for breastfeeding.

You may notice:

  • Increased fullness
  • Tenderness
  • Darker areolas
  • More visible veins

A comfortable supportive maternity bra can help.

Exercise During Week 35

For many women with uncomplicated pregnancies, moderate physical activity can be beneficial.

Suitable activities may include:

  • Walking
  • Swimming
  • Prenatal yoga
  • Light strength exercises
  • Gentle stretching

Avoid activities with a high risk of falling or abdominal injury.

If your healthcare provider has recommended activity restrictions, follow their advice.

Sleep During Week 35

Sleep can become increasingly difficult as your due date approaches.

Your growing belly, frequent urination, heartburn and fetal movement may interrupt your sleep.

Pillows can support your abdomen, back and legs.

A relaxing bedtime routine may also help.

If persistent sleep problems affect your daily life, speak with your healthcare provider.

Prenatal Care

Continue attending your scheduled prenatal appointments.

Your healthcare provider may monitor:

  • Blood pressure
  • Weight
  • Pregnancy symptoms
  • Baby's growth
  • Blood tests
  • Urine tests
  • Medications
  • Prenatal supplements

Depending on your individual circumstances, additional tests or screenings may be recommended.

Preparing for Birth

At Week 35, preparing for labor becomes increasingly practical.

You can:

  • Review what to expect during labor.
  • Discuss your birth preferences with your healthcare provider.
  • Ask about pain-relief options.
  • Keep important documents ready.
  • Confirm transportation to the maternity unit.
  • Finish organizing your hospital bag.
  • Decide who will support you during labor.

Remember that labor does not always follow a predictable plan, so flexibility is important.

Depending on your maternity unit's recommendations, consider:

  • Comfortable clothes
  • Personal hygiene products
  • Phone charger
  • Important documents
  • Comfortable footwear
  • Baby clothes

  • Preparing a safe sleeping space.
  • Keeping essential baby supplies together.

  • Arranging help with household tasks.

You do not need to make everything perfect. Focus on safety and essentials.

Emotional Well-Being

As your due date gets closer, you may experience excitement, nervousness or uncertainty.

You may also think more about labor and how life will change after your baby arrives.

Talk to people you trust about your feelings.

Make time for rest and activities that help you relax.

If persistent anxiety or sadness interferes with your daily life, speak with a healthcare professional.
