Nap lengths vary by age. Newborns (0-3 months) nap 30-90 minutes multiple times a day. Infants (4-11 months) typically nap 30-120 minutes, 2-3 times daily. Toddlers (1-3 years) usually take one 60-120 minute nap. Watch for sleep cues rather than strictly adhering to the clock.

Yes, many studies show that white noise can help babies fall asleep faster and stay asleep longer. It mimics the whooshing sounds they heard in the womb and masks sudden household noises that might startle them. Keep volume at a safe level (below 50-60 dB) and place the sound source at least 6 feet away.

White noise has equal energy at all frequencies (like TV static). Pink noise has more energy at lower frequencies, sounding deeper and more natural — similar to steady rain or rustling leaves. Brown noise is even deeper, resembling a strong waterfall or distant thunder. Many parents find pink and brown noise more soothing for babies.

Consistency is key. Try to put your baby down at roughly the same times each day. Create a mini wind-down routine (dim lights, soft sounds, gentle rocking). Use this timer to track nap duration and avoid overtiredness. Most babies thrive on a predictable rhythm — and soothing sounds can become a powerful sleep cue.

Heartbeat sounds are generally safe and can be very comforting — they replicate the rhythmic thumping your baby heard constantly in the womb. Many newborns are calmed by heartbeat sounds. As with any audio, keep the volume moderate and don't place speakers directly in the crib.

This timer is optimized for nap durations (up to 3 hours). For overnight sleep, you can set a custom time up to 180 minutes as a wind-down timer. The soothing sounds can play independently as long as you need — just keep the tab open and device unlocked for continuous playback.
