How baby sleep develops
In the early weeks, sleep is spread across the whole day and night. Over time, the body clock matures, naps change and longer night stretches may appear.
What affects nights the most
The biggest levers are usually age-appropriate wake windows, total daytime sleep, how bedtime happens and whether your baby needs the same help between sleep cycles.
Night wakings are common
Waking between cycles is physiological. What varies is how often it happens, whether your baby needs feeding and whether they can settle back to sleep.
When to get medical advice
Seek professional advice for breathing issues, poor weight gain, pain, unusual vomiting, persistent fever or any sudden change that worries you.

How many hours should a baby sleep?
There are age-based ranges, but babies vary. Mood, feeding, growth and overall rhythm matter more than a single number.
Is it normal for babies to wake at night?
Yes. Many babies wake between cycles, especially when young. The pattern gradually changes with age.
Should I drop naps to improve night sleep?
Usually not. An overtired baby often sleeps worse, not better.
