Enter your baby's age and morning wake-up time to see an estimated bedtime.
This calculator gives you a starting point for the evening. It uses the age and morning time you enter, rather than your baby's actual naps.
Change either value to update the result. The second card shows the night-sleep range used in the estimate.
This is a starting point, not a fixed bedtime. A shift of 15-30 minutes may help it fit your family routine. It is not medical advice.
The calculation assumes the same wake-up time the next morning. It counts back from that time using the night-sleep range in Baby Soma's age table.
The range is part of the calculation, not a prediction that your baby will sleep for that long without waking.
Use the time to help plan your evening. The calculator does not know when the last nap ended or how your baby is doing.
If the day goes differently, the result will not adjust itself. You can keep actual sleep records in the app.
Enter the morning wake-up time you want to use as a starting point. The calculation assumes the same wake-up time the following morning.
No. It is an estimate based on age and a morning time, not a personal recommendation for tonight.
No. There is no nap input in this calculator. The number and length of today's naps do not change its result.
No. It is the age-table value used to work out the time. It does not predict night wakings or guarantee a length of sleep.
