Newborns generally sleep between 14 and 18 hours a day, waking up frequently for feeds. However, it can be frustrating when a newborn won't sleep after a feed, especially at night. There are many reasons why newborns may not sleep after a feed, including hunger, teething, illness, or being too hot or cold. Additionally, newborns may have difficulty sleeping if they are overtired or if their internal clock is off, causing them to mix up their days and nights. Establishing a consistent bedtime routine, maintaining a comfortable room temperature, and weaning nighttime feeds can help newborns sleep through the night.

Newborns need to feed frequently, so they can't sleep for long stretches
Newborns who sleep for longer stretches should be awakened to feed. Wake your baby every 3–4 hours to eat until they show good weight gain, which usually happens within the first couple of weeks. After that, it's okay to let your baby sleep for longer periods of time at night. If your baby is too sleepy or groggy to rouse themselves every few hours, you will need to wake them to feed to ensure they get enough milk. This will be easier if your baby is in a light sleep cycle.
In the first few days, some babies are sleepy or uninterested in feeding, especially after a difficult labour or birth, or if the mother received drugs for pain relief during labour. Jaundice or an infection may also make a baby sleepy. If your baby is not getting enough milk, they may sleep to conserve energy. If your baby consistently gains less weight than expected, or they haven’t regained their birth weight by 14 days, seek skilled help to assess whether they are getting enough milk.
To help your baby sleep, you can keep the room temperature at around 18°C, or undress them a little if the room is warm. Being too hot can make a baby sleepy. You can also help your newborn learn the difference between day and night by making those times of day very distinct (loud and active during the day, and quiet and soothing at night).

A newborn's internal clock may be off, so they mix up day and night
Newborns generally sleep for around 14 to 17 hours in a 24-hour period, waking up frequently for feedings both day and night. However, their sleep patterns can vary, and some newborns may sleep for up to 18 hours a day. During the first few months, it is common for newborns to wake up multiple times during the night for feedings, which can be challenging for parents.
A newborn's internal clock may be off, causing them to mix up their days and nights. This is a common issue that can be addressed by helping your baby learn the difference between day and night. Here are some strategies to achieve this:
- Make daytime and nighttime distinct: During the day, keep the curtains open, play games, and don't worry about everyday noises while your baby sleeps. At night, keep the lights low, avoid turning on the TV, and maintain a quiet and soothing environment.
- Limit daytime naps: Try to limit your newborn's daytime naps to three hours or less. This will help ensure they are tired enough to sleep at night.
- Establish a bedtime routine: Consistency is key when it comes to helping your newborn fall asleep. Establish a calming bedtime routine and stick to it. This could include activities such as reading a book, singing lullabies, or giving your baby a warm bath.
- Keep your baby awake during feedings: If your baby tends to fall asleep while feeding, try to keep them awake and actively nursing. Offer the second breast if they seem to have finished the first, as they may still be hungry.
- Create a safe and comfortable sleep environment: Ensure your baby's room temperature is comfortable, around 18°C. Keep the room dark and quiet at night to encourage sleep. Use a firm, flat sleep surface with a snug-fitting sheet, and avoid using products that are not specifically designed for sleeping babies, such as feeding pillows or infant loungers.
Remember, it is normal for newborns to have irregular sleep patterns, and their sleep habits will gradually adjust as they grow. Each baby is unique, and some may take longer than others to establish a consistent sleep schedule.

Being too hot or too cold can disturb a newborn's sleep
Newborns generally sleep for 14 to 17 hours in a 24-hour period, waking up frequently for feeds during the day and night. However, being too hot or too cold can disturb a newborn's sleep.
To prevent your baby from getting too hot, keep the room temperature at around 18°C. If the room is warm, consider undressing your baby a little and unwrapping any blankets. Being too hot can make a baby sleepy, and a newborn may sleep longer than is good for them if they are not getting enough food. A baby may also sleep longer than they should if they are apart from you.
On the other hand, a newborn may not sleep well if they are too cold. To prevent this, ensure your baby is dressed appropriately for the weather and their body temperature. It is good to get your baby used to sleeping through a certain amount of noise, so you do not need to worry about keeping the house silent while they sleep.
Additionally, it is important to establish a consistent bedtime routine and differentiate between day and night. During the day, open the curtains, play games, and do not worry about everyday noises when your baby sleeps. At night, keep the baby's room dark when they nap and avoid turning on the TV during nighttime feeds.

Newborns should be awakened to feed every 3-4 hours until they show good weight gain
Newborns have different sleep patterns from adults, and they sleep for about 14 to 17 hours in a 24-hour period. They wake up frequently, both day and night, for feedings and may sleep in short, catnap-like spurts. Newborns need to feed every two to four hours, depending on whether they are breastfed or bottle-fed. Breastfed babies tend to feed more often, about every 2–3 hours, while bottle-fed babies feed less frequently, about every 3–4 hours.
During the first few weeks, newborns are adjusting to life outside the womb and learning the difference between night and day. It is important to make distinctions between day and night to help them learn this difference. For example, keeping the baby's room dark during naps and avoiding screen time during nighttime feedings can help signal that it is nighttime.
Additionally, it is recommended to feed the baby during active or REM sleep. This is when the baby moves their arms and legs, changes facial expressions, and flutters their eyelids. If the baby is in deep sleep, you can try to slowly unswaddle them or change their diaper while singing or talking to them gently.

A baby may sleep longer than is good for them if they are apart from you
Newborns generally sleep between 14 and 18 hours a day, waking up frequently for feeds both day and night. However, this sleep is often in short, catnap-like spurts, and it can be difficult for new parents to adjust to their baby's sleep patterns.
A baby's sleep patterns can be affected by various factors, such as growth spurts, teething, and illnesses. Additionally, newborns need to feed frequently, so they can't sleep for long stretches. They also need to be woken up every 2-4 hours to eat until they show good weight gain, which is usually within the first couple of weeks.
One reason a newborn may not sleep after a feed is that they are not getting enough milk. Newborns need to feed actively from one or both breasts at each feed, swallowing regularly. If a baby is too sleepy to feed effectively, they may need help to ensure they are getting enough milk. This can include waking them up to feed or seeking skilled help if they haven't regained their birth weight by 14 days.
Another reason a baby may not sleep after a feed is that they are apart from their caregiver. In the early weeks, babies often doze off during a feed, and it is important to ensure they are getting enough milk before they fully fall asleep. Room-sharing, where the baby sleeps in the same room as the caregiver, can help with feeding and comforting at night while also reducing the risk of sudden infant death syndrome (SIDS).
Additionally, it is important to create distinct environments for day and night to help your baby learn the difference. During the day, keep the curtains open, play games, and don't worry about everyday noises. At night, keep the lights low, avoid playing or talking to your baby, and use a crib specifically designed for sleeping.
