What is a Pregnancy Time Capsule?

A pregnancy time capsule helps persevere your memories. It tells the story of your pregnancy and how your baby developed. It’s a craft that lasts a lifetime and will be cherished by many.

Not only can you look back at your keepsake, but your baby can too. Once your child grows up, they can reflect on their very beginning. Unlike a pregnancy journal, a pregnancy time capsule encourages you to save memories, showing your journey from a variety of angles.

Consider gifting the time capsule to your baby on their 18th birthday.

How to: DIY Time Capsule Baby Keepsake


  • A container to keep your time capsule items in
  • Time capsule items (suggestions in the next section)
  • Letter to your baby


Step one

First, write a letter to your baby. Keep in mind when you envision them opening the time capsule. If it’s on their 18th birthday, address them as becoming an adult when you write your letter. Make sure to include all your wishes and hopes for them.

Step two

Next, choose a container to store your keepsake items in. Make sure your container is large enough to fit everything you plan on including. If you plan on storing your keepsake somewhere where moisture levels fluctuate (e.g. garage, basement or attic), choose an airtight plastic container. This will prevent your items from getting damp or moldy. If you’re storing your capsule inside your home—like in a closet—you can use a decorative box, like a wooden box.

Step three

Add your letter to your baby and other items to the time capsule. Make sure to include memories that are important to you and that you think your baby will value when they grow up. Aim to paint a story with your capsule and choose your items accordingly. Read the next section for ideas.

Step four

Keep your pregnancy time capsule in a safe place until you’re ready to gift it to your baby or show others. You can also continue adding to the time capsule over the years. If you want, include memories of their newborn days and every year as they grow.

BabyDoppler USB Recording

How special would it be to listen to your baby’s heartbeat once she’s all grown up? That itself is a keepsake to cherish forever. With a fetal doppler, you can capture an audio recording to last a lifetime.

Fetal dopplers are handheld devices that allow you to hear your baby’s heartbeat. You’ve probably seen your doctor use one before in their office. An at home fetal doppler works similarly. You glide the probe to detect a heartbeat, which is amplified through speakers. You can also record your baby’s heartbeat and transfer it to a USB for your keepsake.

How to make a BabyDoppler recording:

  1. If you haven’t already, get a BabyDoppler device
  2. Download the BabyDoppler app
  3. Apply a blob of ultrasound gel to your lower belly
  4. Stick the probe in the gel and turn your device on
  5. Starting low, slowly move the probe in a rocking motion, covering every area of your belly.
  6. Stop when you hear the baby’s heartbeat (read: read: 8 Tips to Discern Fetal Doppler Noises)
  7. Record the heartbeat using the BabyDoppler app (read: Step-by-Step BabyDoppler App Guide)
  8. Save the recording to your device
  9. Email yourself the recording
  10. Download the recording file it on your desktop
  11. Save the recording onto a USB
  12. Place the USB inside your baby keepsake box
