Week 27 of Pregnancy: Sleep Problems and How to Prepare for Childbirth

World
Motherhood

Week 27 marks the end of the second trimester and the beginning of the final stretch of pregnancy. At this stage, the baby continues to grow rapidly and their organs continue to mature, preparing for life outside the womb.


For the mother, this week may bring new physical and emotional changes. The uterus continues to expand, which can cause discomforts such as back pain, leg cramps, and fatigue.

Symptoms

  • Fatigue and lack of energy: The body continues to work intensely, which can lead to increased tiredness.
  • Increased abdominal pressure: The uterus continues to expand and can cause discomfort or a feeling of heaviness.
  • Stronger baby movements: Kicks and turns are more frequent and intense.
  • Swelling in legs and feet: Fluid retention and pressure on the veins can cause inflammation, especially at the end of the day.
  • Back pain: Weight gain and changes in posture can cause discomfort in the lower back area.
  • Leg cramps: More common at night, these may be related to circulation and a lack of minerals such as magnesium or calcium.
  • Heartburn and reflux: Pressure from the uterus on the stomach can cause burning or digestive discomfort.
  • Insomnia or difficulty sleeping: Weight gain, the need to urinate more frequently, and discomfort can affect rest.
  • Increased vaginal discharge: This is normal as long as it does not have a foul odor or an abnormal color.
  • Shortness of breath: The growth of the uterus can press against the diaphragm and make deep breathing a bit more difficult.

Baby Size

In week 27, the baby measures approximately 36 centimeters from head to toe and weighs around 900 grams to 1 kilogram, similar to the size of a cauliflower.

Baby Changes and Development

  • Lung development: Their lungs continue to mature and begin to produce surfactant, an essential substance that will help the baby breathe on their own after birth.
  • Growing brain: Their brain is developing rapidly, forming more neural connections and improving their reflexes.
  • Increased sensitivity to stimuli: They can react to light and sound, responding with movements or changes in their heart rate.
  • Opening of the eyes: Their eyelids, which were previously closed, begin to open and they can blink.
  • More defined movements: The baby is more active and their kicks and turns are more noticeable. They can also respond to touch if the belly is stroked.
  • Fat accumulation: Their skin, which was previously thinner and wrinkled, begins to thicken with the accumulation of subcutaneous fat, which will help them regulate their temperature at birth.
  • Fetal hiccups: It is common for the mother to feel small rhythmic movements as the baby begins to practice breathing, which can cause episodes of hiccups.

What Should You Do?

  • Attend prenatal check-ups
    The doctor may request a glucose test to rule out gestational diabetes.
    Blood pressure and weight should be monitored to prevent complications such as preeclampsia.
  • Maintain a healthy diet
    Maintain a balanced diet rich in protein, calcium, iron, and fiber to support the baby’s growth and prevent digestive issues like constipation.
    Drink enough water to stay hydrated and reduce fluid retention.
  • Maintain a moderate exercise routine
    Engage in physical activity such as walking, prenatal yoga, or swimming to improve circulation, reduce stress, and strengthen muscles for childbirth.
  • Take care of rest and posture
    Sleep on your side, preferably on the left side, to improve circulation and avoid compression of the vena cava.
    Use pregnancy pillows or place one between your legs for greater comfort.
  • Prepare for the baby’s arrival
    It is a good time to start organizing the hospital bag and preparing the space where the baby will sleep.
    Consider taking a childbirth preparation course to learn breathing and relaxation techniques.
  • Manage stress and take care of emotional health
    Practice relaxation techniques such as meditation or deep breathing.
    Express emotions and maintain open communication with your partner or family members to feel supported during this stage.

Nutrition in Week 27 of Pregnancy

Increase Iron Intake
Blood volume continues to increase, so it is key to consume iron-rich foods to prevent anemia:
Lean meats (chicken, turkey, beef)
Legumes (lentils, chickpeas, beans)
Green leafy vegetables (spinach, chard, broccoli)
Nuts (almonds, walnuts)
It is recommended to combine these foods with sources of vitamin C (orange, strawberries, kiwi) to improve iron absorption.

Include Sufficient Calcium
The baby needs calcium to strengthen their developing bones and teeth. Recommended sources:
Dairy (milk, yogurt, cheese)
Almonds
Broccoli
Tofu

Ensure Good Protein Intake
Proteins help with the baby’s growth and the formation of their tissues. It is recommended to consume:
Chicken, fish, and eggs
Legumes
Nuts and seeds

Consume Healthy Fats
Healthy fats support the baby’s brain development and help maintain optimal energy levels:
Avocado
Olive oil
Fatty fish (salmon, sardines)
Nuts

Increase Fiber and Hydration
Constipation is common at this stage, so fiber should be included in the diet and enough water should be consumed:
Fresh fruits and vegetables
Whole grains (oats, brown rice, whole-wheat bread)
Legumes

Avoid Ultra-processed and High-sugar Foods
It is recommended to reduce the consumption of refined sugars, white flours, and processed foods to prevent excessive weight gain and gestational diabetes.

Improves Mood
Exercise stimulates the production of endorphins, promoting a sense of well-being and reducing symptoms of anxiety and depression.

Helps Regulate Intestinal Transit
Physical activity promotes bowel movement, reducing the risk of constipation, a common problem in the third trimester.

Recommended Exercises:
Daily walks of 20 to 30 minutes
Prenatal yoga
Swimming
Kegel exercises to strengthen the pelvic floor
Gentle stretching

Exercise in Week 27 of Pregnancy

Improves Circulation and Prevents Swelling
Exercise promotes blood flow, which helps reduce swelling in the legs and feet, as well as decreasing the risk of developing varicose veins.

Decreases Back Pain
Stretching routines, prenatal yoga, and muscle-strengthening exercises help relieve pressure on the lower back and improve posture.

Supports Weight Control
Exercise contributes to maintaining healthy weight gain, reducing the risk of complications such as gestational diabetes and hypertension.

Helps Improve Sleep
Staying active helps reduce stress and anxiety, which promotes deeper and more restorative rest.

Facilitates Labor
Low-impact exercises strengthen the pelvic floor muscles and improve physical endurance, which can help lead to a smoother labor with fewer complications.

Things You Should NOT Do:

Avoid Carrying Heavy Objects
Lifting excessive weight can put pressure on the back and abdomen, increasing the risk of injury or premature contractions.

Do Not Stand or Sit for Long Periods Without Moving
Spending long periods in the same position can affect circulation and increase swelling in the legs and feet. It is recommended to move every so often and elevate the legs when possible.

Do Not Consume Raw or Undercooked Foods
To prevent infections such as toxoplasmosis or listeriosis, it is essential to avoid:
Raw meats, fish, or shellfish
Undercooked eggs
Unpasteurized dairy
Cold cuts and deli meats without prior heating

Do Not Sleep on Your Back
At this stage, sleeping on your back can compress the inferior vena cava, which can cause dizziness and affect the baby’s circulation. It is recommended to sleep on your side, preferably on the left side.

Avoid high-impact exercises or those with a risk of falling
Sports such as running, jumping, skiing, or cycling on uneven terrain can increase the risk of falls or blows to the abdomen.

Do not self-medicate
Any medication, supplement, or treatment must be authorized by a doctor, as some can be harmful to the baby.

Do Not Expose Yourself to Extreme Temperatures
Saunas, hot tubs, or very hot baths can raise body temperature and affect the baby’s development.

Avoid Excessive Stress
Anxiety and stress can affect maternal and fetal well-being. It is recommended to practice relaxation techniques such as deep breathing, yoga, or meditation.
