Why Hiccups Help Strengthen Baby’s Breathing Muscles

During pregnancy, you may feel tiny, rhythmic jumps inside your belly, which are foetal hiccups. While they might seem surprising initially, they're actually a healthy sign of your baby's development. Foetal hiccups play a crucial role in fortifying your baby's breathing muscles, preparing them for life after birth. Understanding the reason behind these hiccups and what they mean helps you stay calm, in a loop, and confident during your pregnancy.

Pregnancy brings many new sensations, but few are as fascinating as the small, rhythmic movements that feel like subtle taps from within. When you first feel those little flutters, you might wonder what’s going on inside you. The good news is, those tiny, rhythmic movements are often just foetal hiccups, and they actually help your baby get ready to breathe properly after birth.
Let's look at how babies get hiccups, how it helps them grow, and what you should know if you’re having a baby.

What Do Foetal Hiccups Mean?

Foetal hiccups are tiny, repetitive contractions of your baby's diaphragm, the muscle that supports breathing. Just like adult hiccups when the diaphragm contracts suddenly, babies do the same inside the womb.
  • Baby hiccups commonly feel like:
  • Rhythmic, tiny jumps
  • Repetitive tapping
  • Movements are happening at regular intervals
They usually begin from the second trimester, although they may be more noticeable in the last few months when your baby's movements get more intense.

How Do Hiccups Help Strengthen Your Baby’s Breathing Muscles?

1. Do Hiccups Help Strengthen the Diaphragm?
Yes. Every hiccup contracts your baby's diaphragm, helping this significant muscle develop strength and coordination. In fact, this rhythmic movement prepares the diaphragm for the first big breath your baby will take after they're born.

2. Do They Improve Lung Function?
During hiccups, your baby practices moving amniotic fluid in and out of the lungs. While it's not real breathing, this movement helps:

  • Promote lung maturity
  • Expand the lung sacs
  • Support better respiratory development

Research indicates that babies begin these practice breathing movements as early as 9 to 10 weeks, and that hiccups are a form of exercise.

3. Do Hiccups Support the Nervous System?
Yes, they help your baby's brain learn how to regulate breathing patterns. This sync between the brain and the diaphragm becomes more intense when a hiccup occurs.

Why Are Foetal Hiccups More Frequent at Certain Stages?

During the mid to late stages of pregnancy, you may sense hiccups more frequently. This actually happens because:

  • Your baby's nervous system becomes more active
  • The diaphragm gets strengthened
  • Lung development peaks between 24 to 36 weeks

Do Foetal Hiccups Indicate a Healthy Development?

Mostly, yes. Foetal hiccups are one of those multiple signs that your baby's lungs and diaphragm are developing in a healthy way. They show that your baby is practising essential movements required for breathing after they're born. However, every pregnancy is unique. Some babies hiccup regularly, while others hardly do, and both can be normal.

What to Expect When You Sense Foetal Hiccups?

You might sense hiccups:

  • Once or twice a day
  • A few times a week
  • For a few minutes at a time

Most episodes last 1 to 5 minutes. They should feel subtle, repetitive, and not painful.

Hiccups usually occur when:

  • You had your meals
  • You are resting
  • Your baby is active
  • You drink something cold

When Can Baby Hiccups Be Alarming?

Baby hiccups are usually not a big deal, but certain scenarios may require a proper consultation. Call your doctor if:

  • The hiccups start happening much more often after week 32 or 34
  • You feel them more than 3 to 4 times every day, nonstop
  • They regularly stick around for over 15 minutes
  • The hiccups feel extremely strong or bother you
  • Your baby’s not moving like they usually do

How Can You Make Yourself Comfortable with Baby Hiccups?

Your baby’s hiccups aren’t something you can control, but there are certain measures you can take to make this time comfortable for both of you:

  • Keeping yourself relaxed physically by staying nourished
  • Trying a side-lying position to see if that helps
  • Breathing slowly to keep yourself calm
  • Gently rub your belly to calm the baby inside you

What’s the Next Step?

  • Monitor the rhythm of your baby’s hiccups
  • Stay relaxed, most hiccups are healthy and normal
  • Keep track of overall foetal movement
  • Make sure you attend all your prenatal appointments
  • Call your doctor if anything feels strange
  • Keep up a healthy lifestyle for the baby’s development

Social & Emotions Aspects

Feeling your baby’s hiccups can bring all sorts of emotions to you, like happiness, curiosity, or even a little worry, all at once. Discussing these feelings with your partner or family can offer you support or help you stay comforted by their presence during this time. These little movements also help you feel close to your baby. Many parents describe hiccups as one of the most memorable parts of pregnancy.

Foetal hiccups are one of the most memorable experiences of your pregnancy journey. They play a vital, practical role in strengthening your baby's breathing muscles and preparing them for life after they're born. While they're mostly harmless, staying watchful of the rhythms and knowing when to seek medical advice helps you stay prepared and informed. With the right knowledge and reassurance, you can enjoy these gentle reminders of your baby's growth.
