What the results mean
The cards show a range for time awake during the day, a daytime nap count and a separate range before night sleep.
These are reference values for an age group. The calculator does not use your baby's recent sleep records.
Time awake between sleeps
Choose your baby's age to see a starting point for time awake and daytime naps.
A wake window means the time between waking up and falling asleep again. It includes feeding, playing and getting ready for sleep.
Choose the age in months. The results update straight away using Baby Soma's age table.
Time awake between sleeps (4 months)
1h 50m - 2h 15m
Daytime naps
4 naps
Time awake before night sleep
2h 5m - 2h 15m
This is a starting point from Baby Soma's age table, not a rule for your baby. Watch how your baby is doing. Ask a pediatrician about health concerns. For a baby born 3 or more weeks early, use the corrected age (counted from the due date) until age 2.
How to use the range
Count from when your baby wakes up. The time shown is a starting point for planning, not a deadline to reach.
Your baby's day may look different. The result does not tell you whether a particular sleep was good or bad.
Common questions
What does “wake window” mean?+
It is the time your baby is awake between sleeps, including feeds and play.
Do I need to follow the range exactly?+
No. It is a reference from an age table, not a personal sleep plan. Take your baby's needs into account.
Why is there a separate result before night sleep?+
The table has a separate range for the time after the last nap and before night sleep. It may differ from the daytime range.
Can I use this for a newborn?+
Yes. Select the youngest age in the calculator. The result remains a general guide, not a fixed routine.
Is this medical advice?+
No. The calculator does not assess health or diagnose sleep problems. Discuss health concerns with a pediatrician.
