Create the perfect sleep environment. A white noise machine helps babies settle and stay asleep longer by masking household sounds.
Baby sleep is guided by wake windows — the amount of time a baby can comfortably stay awake before needing to sleep again. Too short a wake window = baby not tired enough to settle. Too long = overtired baby who fights sleep. Wake windows gradually lengthen as babies develop.
The NHS and American Academy of Sleep Medicine (AASM) provide total sleep recommendations. Individual babies vary significantly — some naturally need more or less sleep than average. A baby who sleeps slightly less but seems happy, alert and developing well is generally fine.
FAQs
When overtired, the body releases cortisol (a stress hormone) to maintain wakefulness. This makes it harder to fall asleep, not easier. An overtired baby often seems wired, hyperactive or inconsolably upset. The fix is to catch sleep before this point — watch for tired cues (yawning, eye rubbing, staring, fussiness) and respond before the overtiredness escalates.
There's no universal answer — "sleeping through" is often defined as a 5–6 hour stretch, not necessarily 8+ hours. Many babies achieve this between 4–6 months; some not until much later. Night waking is developmentally normal until well into the second year. Factors include feeding method, sleep associations, temperament and developmental leaps. Night waking that's sudden and new after good sleep often signals a leap, illness or developmental milestone.
Babies who sleep somewhat more than average are usually fine, especially in the early weeks. However, in the first 6 weeks, a baby sleeping excessively (so much they're difficult to wake for feeds) may not be getting adequate nutrition. Newborns need feeding every 2–3 hours regardless of sleep. If you can't wake your baby for feeds, or they seem very lethargic, contact your midwife or GP.
