What is normal
- Newborns sleep about 14 to 18 hours in 24, in blocks of 1 to 4 hours, with no day or night yet.
- The longest sleep tends to move to the night around 3 to 4 months. By 3 to 4 months many babies manage a 5-hour stretch, but plenty do not until later. Sleeping through the night early is rare.
- Growth spurts, teething and illness will mess up any routine. That is not you failing.
Help days and nights tell apart
- Days: light, noise, normal life.
- Nights: dark, quiet, boring. Keep night feeds and diaper changes calm and low-light.
- A short calm bedtime routine (even for a newborn) starts a habit that pays off later.
Split the nights
Sleep deprivation raises irritability and anxiety and raises the risk of depression, so sleep is part of postpartum mental health. A simple fix many couples use: one parent is "on" for the first half of the night, the other for the second half, and the "off" parent uses earplugs. A protected stretch of 4 to 5 hours for each of you is a sensible target, not a rule.
- Breastfeeding? The non-nursing parent can do diapers and burping, then bring baby back to feed. After feeding is established, they can also give a bottle of expressed milk.
- Rest when baby sleeps when you can, and let the dishes go.
- Insomnia even when baby is asleep can be a sign of anxiety or depression. Tell your doctor.
Sleep training
Most guidance suggests waiting until about 4 to 6 months before any formal sleep training, and only after talking with your pediatrician. In the early weeks, responding to your baby builds trust. You cannot spoil a newborn.

Education, not medical advice. Every baby and every parent is different. Ask your own doctor, midwife or pediatrician about anything specific to you, and call them or emergency services if you are worried.
