Totals are wide on purpose
Healthy babies vary a lot. The recommended ranges are deliberately broad, so a baby who sleeps a little less or more than the middle of the range is usually doing just fine if they are generally content and growing well.
Consolidation matters more than the total
In OBubba’s own analysis of anonymised logs, the babies who slept best were not the ones with the most total sleep. They had longer unbroken stretches at night. That is why the app focuses on bedtime timing and night stretches, not just hours.

Questions parents ask
Frequently asked questions
How many hours should a newborn sleep?
Newborns typically sleep around 14 to 17 hours in 24, in short stretches spread through the day and night.
How much should a 6 month old sleep?
Around 12 to 16 hours in 24, often 10 to 12 at night with the rest across about three naps.
My baby sleeps less than the chart. Is that a problem?
Not usually. If your baby is mostly content, feeding and growing well, they are likely getting what they need. If you are worried, your health visitor is a good person to ask.
