If your baby is not sleeping at night, it can be exhausting and frustrating. Many parents face this problem, especially in the first year.

In most cases, poor night sleep is caused by hunger, overtiredness, poor sleep habits, or developmental changes. The key is to understand what’s causing the issue and adjust your baby’s routine.

1. Hunger
Young babies often wake frequently because they need feeding.

2. Overtiredness
When a baby stays awake too long, it becomes harder to fall asleep and stay asleep.

3. Sleep associations
Babies may depend on rocking or feeding to fall asleep and wake up when conditions change.

4. неправильные wake windows
Incorrect timing between sleep periods can disrupt night sleep (see baby wake windows by age).

5. Inconsistent schedule
A lack of routine can lead to fragmented sleep (see baby sleep schedule by age).
