Better Sleep for Baby and You
Background sound is one of the most effective and low-cost ways to help a baby sleep. The Baby Sound Machine generates six different sounds directly in your browser using audio synthesis — no files to download, no streaming service to pay for. You can play white noise on its own for a simple, consistent background, mix in rain and ocean waves for a more natural soundscape, or add the rhythmic shushing sound that mimics what babies heard in the womb. Each sound has its own volume slider, so you can fine-tune the mix. The fullscreen night-light mode turns your screen into a soft, colored glow — perfect for nighttime feedings or as a visual cue that it is sleep time. Set the sleep timer and the sounds fade out automatically.
Track Your Pregnancy with Confidence
Weight gain during pregnancy is one of the most common topics expectant parents have questions about, and the answer varies based on your pre-pregnancy BMI. The Pregnancy Weight Gain Tracker uses the Institute of Medicine guidelines to show you a personalized recommended range, then plots your actual weekly weights against that range on a clear visual chart. You can see at a glance whether you are on track, and the entry log keeps a complete record you can export as a CSV to share with your healthcare provider.
Frequently Asked Questions
Is white noise safe for babies?
White noise can be a helpful sleep aid for babies when used responsibly. The American Academy of Pediatrics recommends keeping sound machines at a moderate volume (under 50 decibels at the baby's ear, roughly the level of a quiet conversation) and placing them at least 7 feet from the crib. Our Baby Sound Machine lets you control the volume precisely and mix different sounds to find what works best for your child.
How much weight should I gain during pregnancy?
Recommended pregnancy weight gain depends on your pre-pregnancy BMI. The Institute of Medicine guidelines suggest 28-40 lbs for underweight women, 25-35 lbs for normal weight, 15-25 lbs for overweight, and 11-20 lbs for obese. Most weight gain occurs in the second and third trimesters. Our Pregnancy Weight Gain Tracker calculates your BMI category and shows your progress against the recommended range on a visual chart.
Do these tools store my personal data?
No. Every tool runs entirely in your browser. We do not collect, store, or transmit any of your personal or health data. The Pregnancy Weight Gain Tracker uses localStorage so you can save progress between sessions, but that data stays on your device and is never sent to a server. There are no accounts, no sign-ups, and no usage limits.
Can I use the sound machine on my phone?
Yes. The Baby Sound Machine works on mobile browsers including Safari on iPhone and Chrome on Android. The fullscreen night-light mode is especially useful on tablets placed near the crib. Note that some mobile browsers may pause audio when the screen locks or the app is backgrounded — keeping the browser tab active ensures uninterrupted playback.
How is a pregnancy due date calculated?
The most common method is Naegele's rule: add 280 days (40 weeks) to the first day of your last menstrual period. Our Due Date Calculator also supports conception date, IVF transfer dates, and ultrasound-based calculations. It shows your gestational age, trimester, progress bar, and key milestones like the anatomy scan window and full-term date.
What is the 5-1-1 rule for contractions?
The 5-1-1 rule is a guideline for when to head to the hospital: contractions come every 5 minutes, last about 1 minute each, and this pattern continues for at least 1 hour. Our Contraction Timer automatically detects this pattern and shows an alert. Every pregnancy is different, so always follow your healthcare provider's specific instructions.
