When Can I Hear My Baby’s Heartbeat and Breathing?

Expectant parents often look forward to hearing their baby’s heartbeat and eventually their breathing, as these are some of the earliest signs of life and development in the womb. Both experiences are important milestones in pregnancy, and thanks to advancements in antenatal care, parents can experience these moments earlier and more accurately than ever before. In the UK, antenatal scans and checkups are standard practice and offer an opportunity to monitor your baby’s growth and wellbeing, which includes hearing their heartbeat and assessing their lung development.

In this article, we’ll discuss when you can expect to hear your baby’s heartbeat, the tools and scans involved, and whether it’s possible to hear your baby’s breathing before birth. We’ll also explore the role of antenatal appointments in these milestones and how to prepare for these special moments. As always, your healthcare provider will be your best resource for specific information regarding your pregnancy.

When Can You Hear Your Baby’s Heartbeat?

Hearing your baby’s heartbeat for the first time is a magical moment that many parents cherish. The development of your baby’s heart happens early in pregnancy, and antenatal scans and checkups provide a way for healthcare providers to listen and monitor it. Generally, you can hear your baby’s heartbeat between 6 and 9 weeks of pregnancy.

The First Antenatal Scan: The Early Viability Scan

The early viability scan is typically performed between 6 and 10 weeks of pregnancy, and it’s usually during this scan that you can first hear your baby’s heartbeat. This scan, often called a dating scan, uses high-frequency sound waves to produce an image of the baby inside the womb. With the help of a transvaginal ultrasound, the scan can detect the heart’s early flickers, and you may be able to hear the heartbeat as well.

At this stage, the baby’s heart is still developing, and the heartbeat will likely sound fast—often between 110 to 160 beats per minute. This scan also helps confirm the number of babies, whether the pregnancy is progressing normally, and your estimated due date.

What if I Can’t Hear the Heartbeat?

It’s important to note that some women may not be able to hear their baby’s heartbeat at the first scan, especially if the pregnancy is earlier than expected. In most cases, this is normal, and your healthcare provider may recommend waiting another week or two for a follow-up scan to check the heartbeat again.

The 12-Week Antenatal Scan: The Dating Scan

The next significant scan occurs around 12 weeks, known as the dating scan. By this time, your baby’s heart is much more developed, and it’s very common to hear the heartbeat during this scan using an abdominal ultrasound. This scan also helps monitor other key developmental aspects of the baby, such as organ formation, as well as confirming the gestational age.

Hearing your baby’s heartbeat during the dating scan is a reassuring sign that your pregnancy is progressing as expected. Antenatal appointments at this stage are also essential to assess your overall pregnancy health, monitor for any complications, and plan for the rest of your pregnancy journey.

When Can You Hear Your Baby’s Breathing?

Unlike hearing your baby’s heartbeat, hearing your baby’s breathing before birth is a bit more complicated. Babies don’t technically breathe in the womb in the way they do after birth because their lungs are filled with amniotic fluid rather than air. However, their lungs begin developing early, and antenatal scans can detect the baby practising “breathing” movements as they prepare for life outside the womb.

Lung Development in the Womb

Around the 24-week mark, your baby’s lungs will begin to develop further and start practising breathing movements. These movements help develop the muscles needed for breathing after birth, although the baby is not yet breathing air. This process is known as fetal breathing movements, and they involve the baby’s diaphragm contracting and relaxing, imitating the motions they will use to breathe once born.

Though you won’t be able to hear these movements as you would with a heartbeat, your healthcare provider will check for them during antenatal scans to ensure your baby’s lungs are developing properly. These movements are a strong indicator of your baby’s health and preparedness for life outside the womb.

Can You Hear Baby Breathing Before Birth?

Unfortunately, there is no way to hear your baby’s breathing before birth, as their lungs are still filled with fluid. However, technology allows us to observe these breathing-like movements through scans, ensuring that everything is progressing normally. After birth, the baby’s first breath will be a significant milestone, and it is typically heard immediately after delivery.

The Role of Antenatal Appointments and Scans in Hearing Your Baby’s Heartbeat and Breathing

Your antenatal appointments and scans play a crucial role in monitoring your baby’s heart and lung development throughout your pregnancy. These appointments help to ensure that your baby is growing healthily and that any potential issues are identified and addressed as early as possible.

During routine antenatal care, your midwife or doctor will use a Doppler device to listen to your baby’s heartbeat. The Doppler is a handheld ultrasound device that amplifies the sound of your baby’s heartbeat, allowing you to hear it clearly. These checkups are a regular part of your pregnancy care and provide reassurance that your baby’s heart is beating strongly.

Key Antenatal Milestones for Heartbeat and Lung Development

6-9 Weeks: Heartbeat can be detected during the early viability scan.

12 Weeks: The dating scan is another opportunity to hear the heartbeat and check your baby’s growth.

24 Weeks: Lung development continues, and antenatal scans can detect fetal breathing movements.

28-40 Weeks: Regular antenatal checkups will continue to monitor the baby’s heart rate using a Doppler.

Importance of Antenatal Education

Antenatal classes can also help you understand the various milestones of your baby’s development. These classes offer education on what to expect during your pregnancy, labour, and delivery. They cover topics like when you can hear your baby’s heartbeat, how their lungs develop, and how to manage the various stages of pregnancy.

Many parents also find support in antenatal yoga or prenatal yoga classes, which are designed to help improve flexibility, strength, and relaxation during pregnancy. These exercises can support overall wellbeing, which is important for both the mother and baby’s health.

Prenatal and Antenatal Support

It’s essential to stay informed about your pregnancy and attend all of your antenatal appointments. These regular visits allow your midwife or doctor to monitor your baby’s growth and development and identify any potential concerns. In addition to medical checkups, taking antenatal vitamins and practising self-care, such as prenatal massage or relaxation techniques, can support a healthy pregnancy.

Antenatal Clinic Visits and Preparing for Birth

In the UK, attending your scheduled antenatal clinic visits is an important part of maintaining your pregnancy care plan. These visits will often include routine scans and checkups to monitor your baby’s heart and lungs. It’s during these appointments that you will hear your baby’s heartbeat and learn about their lung development, preparing you for a healthy and successful delivery.

Hearing your baby’s heartbeat is one of the earliest and most exciting milestones of pregnancy. It’s a clear sign that your baby is developing well and growing strong. Though you can’t hear your baby’s breathing in the womb, knowing that they’re practising breathing movements helps to reassure you that their lungs are preparing for life outside.

Your antenatal care is crucial in monitoring these developments. From your first scan to your routine checkups, these appointments give you the opportunity to experience these incredible moments and ensure that both you and your baby are healthy. Always consult your healthcare provider for specific advice about your pregnancy and be sure to attend all your scheduled antenatal appointments for peace of mind and optimal care.
