Going to bed for a 4:50 am alarm

Asleep by 7:35 pm — 6 full sleep cycles, about 9 hours
Asleep by 9:05 pm — 5 full sleep cycles, about 7 hours
Asleep by 10:35 pm — 4 full sleep cycles, about 6 hours

A sleep cycle runs about 90 minutes, and most people take around 15 minutes to drop off. Waking at the end of a cycle feels easier than waking in the middle of one.

Online alarm clock for 4:50 am

As you finish the baby’s 4:50 am feed and head back to bed, set the alarm for the next scheduled feeding before leaving the nursery. With 5:00 am close by, it is easy to postpone the small task and then lose track of it once the bottle is rinsed, the light is off and the house is quiet again.

The feeding alarm needs to be heard beyond the room where it was set, so check where its sound will play. A phone may quietly remain connected to earbuds or wireless headphones, sending the alert somewhere no one can hear it. Disconnect them or test the alarm at a low volume before settling down. A browser alarm only works while it remains active; if it is closed or the phone falls asleep, the baby’s next feeding cue will not sound.

After leaving a night feed, keep the return to bed brief and uneventful: dim the hallway, put the bottle and cloth in their usual place, and avoid starting chores under bright kitchen lights. At 4:50 am, even a short tidy-up can eat into the sleep still available before the household begins moving. Having the essentials ready for later lets you get under the doona again without another search through cupboards.

Common questions

Can I use this on my phone instead of a laptop?

Yes, it works in a mobile browser the same way, but phones are more likely to lock the screen or sleep, which can stop the alarm from ringing. A laptop or desktop tends to be more reliable for this.

Can I set more than one alarm at a time?

This page is built around a single alarm at a time. For multiple alarms, open a separate tab for each one and set a different time in each, keeping every tab open until it's rung.

Why use a browser alarm instead of my phone's built-in one?

Mainly for reliability against silent mode, do-not-disturb, or a phone left charging out of earshot. It's a useful backup or a desk-based alternative, though it depends on this tab staying open rather than running in the background of your phone.

Is there a cost to use this?

No, it's free, with no sign-up and no limit on how many times you set it. It just needs the tab left open until the time you've chosen arrives.
