How Big Is a Baby at 8 Weeks?
At 8 weeks, your baby is starting to look a bit more like a tiny human — just much smaller. So, how big is a baby at 8 weeks? On average, the size of baby at 8 weeks is comparable to a raspberry or a kidney bean.
Average Length and Weight at 8 Weeks
In terms of measurements, your little one is about 13 to 16 millimeters long and weighs approximately 1 gram — barely the weight of a paperclip! Even though this may seem small, the growth happening week by week is remarkable. In fact, the baby size at 8 weeks is almost double what it was just a week ago. As you progress, you’ll notice these changes continue rapidly, laying the foundation for all major body systems. So, if you’re curious about how big is baby at 8 weeks, think of something small but mighty — because a lot is happening inside that tiny frame. “Wondering what changes to expect as you near the end of pregnancy?

What Does a Baby Look Like at 8 Weeks?
If you’re wondering what a baby looks like at 8 weeks, the answer might surprise you. Though still tiny, your baby is starting to take on a more recognizable human shape. At this stage, the major body parts are beginning to form, including the head, arms, and legs. The head is disproportionately large compared to the rest of the body, but that’s normal for this point in development. “Curious about your baby’s growth and early labor signs?

Visible Features and Body Shape
In addition to limb formation, the baby’s eyes, nostrils, and ears are starting to develop, giving more definition to the face. Meanwhile, paddle-like hands and feet are growing at the ends of the limb buds, and the curved spine is becoming more noticeable. Even though the features are still in their early stages, they are gradually forming the foundation of your baby’s facial and body structure. So, what does a baby look like at 8 weeks? Think of a miniature, curled-up figure with rapidly evolving features — full of promise and potential.
Baby’s Heartbeat at 8 Weeks: What’s Normal?
One of the most exciting milestones during early pregnancy is hearing your baby’s heartbeat at 8 weeks. By this stage, the baby’s heart rate at 8 weeks typically ranges between 140 to 170 beats per minute (bpm), which is significantly faster than an adult. This rapid pace, in fact, supports your baby’s fast growth and development.
When Can You Hear the Baby’s Heartbeat?
The baby heartbeat at 8 weeks can be detected via a transvaginal ultrasound. While some parents may hear it slightly earlier or later depending on factors such as the position of the uterus or how far along the pregnancy truly is, around 8 weeks is a common benchmark. Moreover, it’s important to understand that the baby’s heart rate at 8 weeks may vary slightly. In some cases, consistently irregular or slow heart rates might require additional monitoring. Nevertheless, your doctor will help interpret these findings accurately. Ultimately, that first audible thump offers both reassurance and joy—it’s a tiny sound with a huge emotional impact. “Planning a special celebration?

Can You Feel Baby Move at 8 Weeks?
At 8 weeks pregnant, you may be eagerly waiting for that first little kick or flutter. However, even though fetal movement has technically begun, it’s still far too subtle for you to notice. The baby is only about the size of a raspberry and is just starting to form muscles and nerves. Therefore, while the movements are happening, they’re not yet strong enough to be felt from the outside.
In most cases, moms begin to feel noticeable baby movements—often called “quickening”—between 16 and 25 weeks of pregnancy. First-time moms may feel it a bit later than those who have been pregnant before. So, if you’re wondering, “Can you feel baby move at 8 weeks?”, the answer is no—not yet. But rest assured, those exciting flutters are on their way in just a few more weeks. “For a medically-reviewed overview of your baby’s development at 8 weeks, visit the NHS week-by-week pregnancy guide.”
No Heartbeat at 8 Weeks – Could Baby Still Be Alive?
Hearing your baby’s heartbeat for the first time is a powerful and emotional milestone. But what if there’s no heartbeat detected during your 8-week ultrasound? Before jumping to conclusions, it’s important to understand that several factors might explain this. For instance, the ultrasound equipment may not be sensitive enough, the timing could be slightly off (especially if ovulation occurred later than expected), or a tilted uterus may make detection more difficult.
In many cases, doctors recommend waiting another week and repeating the ultrasound to confirm. So, if you’re wondering, “No heartbeat at 8 weeks—could baby still be alive?”, the answer is yes, it’s possible. However, it’s also important to stay in close contact with your healthcare provider. A follow-up scan is often essential to determine whether the pregnancy is progressing normally or if further evaluation is needed. “To explore what’s happening during week 8 of pregnancy in more detail, check out this helpful guide from What to Expect.”
Baby at 8 Weeks Ultrasound – What You’ll See
At 8 weeks pregnant, your first ultrasound is often an exciting and reassuring experience. Typically, a transvaginal ultrasound is used at this early stage, as it provides a clearer image than an abdominal scan. During the baby ultrasound at 8 weeks, your provider may point out key structures such as the gestational sac, fetal pole, yolk sac, and—most exciting of all—a flickering heartbeat. “For a deeper look into your baby’s development and symptoms at 8 weeks pregnant, visit this comprehensive guide on BabyCenter.”

As part of the experience, your doctor will measure the crown-rump length to confirm your due date. So, if you’re wondering what to expect from a baby at 8 weeks ultrasound, know that while your little one is still tiny, seeing that rhythmic flicker can be incredibly reassuring and emotional. “To explore more about what’s happening with your baby and your body at week 8, check out this medically reviewed resource on KidsHealth.”

When to Call Your Doctor
While many symptoms during early pregnancy are normal, it’s crucial to know when something may require medical attention. You should call your doctor if you experience heavy bleeding, severe cramping, or a sudden loss of pregnancy symptoms, as these could be signs of complications. Additionally, if your healthcare provider hasn’t already scheduled an early ultrasound, they may recommend one if you have a history of pregnancy issues or concerning symptoms. Remember, prenatal care plays a vital role in monitoring both your health and the development of your baby. It’s always better to reach out with concerns rather than wait, even if everything turns out to be fine. “For a helpful guide on your baby’s growth and changes at this stage, visit this 8-week development article on Emma’s Diary.”
