A newborn does not sleep in one long block, and is not meant to. In the first weeks they sleep in short stretches around feeds, with no sense yet of day and night. NHS guidance says total daily sleep varies but can be around 18 hours, and that babies wake at night because they need feeding.
Frequent feeding drives most of it. NHS guidance says your baby may want to feed perhaps every hour to begin with, and that as a very rough guide a baby should feed at least 8 to 12 times, or more, every 24 hours in the first few weeks. Night feeds also help build your milk supply. The second night after birth is often the hardest, when many babies wake, cry and feed almost constantly.
What Helps in the Early Weeks
- Hold your baby skin to skin. UNICEF UK Baby Friendly guidance says it regulates a baby's heart rate, breathing and temperature, and calms you both. Stay awake, sit propped up, and keep your baby's face uncovered.
- Feed when your baby asks, not to a clock. Turning the head, mouthing and hands to mouth all come before crying.
- Judge feeding by nappies, not by crying. From day 5 onwards, the NHS says to expect at least 6 heavy, wet nappies every 24 hours. If that does not match what you see, speak to your midwife or health visitor the same day.
- Follow safer sleep rules for every sleep, however tired you are. The Lullaby Trust advises putting your baby on their back in their own clear, flat, firm sleep space, in your room, with the room between 16 and 20°C. Never fall asleep on a sofa or armchair with your baby. The Lullaby Trust says this significantly increases the risk of sudden infant death syndrome (SIDS).
- Keep nights dull and days normal. Low light and quiet voices at night, open curtains and everyday noise in the day.
A fixed schedule can wait. Wake-window age charts come from sleep coaching, not national NHS guidance. Newborns do show when they are tired: NHS Healthier Together lists fussing, crying and rubbing eyes, so watch your baby rather than the clock. Keep visits short, rest when you can, and ask for help early.
