Every child is different when it comes to how much sleep they need, and when they have it. Some babies sleep a lot while others simply don’t.
This timeline gives you an idea of how much sleep your little one may need over the next three years and how her sleep and nap patterns will change as she grows.

 | Baby |
|---|---|
| Newborn | Around 16 to 17 hours (over a 24-hour period) (NHS 2017). Day: six to eight hours (NHS 2017). Night: eight to nine hours (NHS 2017). Newborns sleep almost as much during the day as they do at night (NHS 2017) . Your baby probably won’t stay sleep for more than two or three hours at a time during the day (BASIS nd). This is because she needs to wake often for a feed. |
| One to two months | Around 14 to 16 hours (NHS 2017). Day: six to seven hours (NHS 2017). Night: eight to nine hours (NHS 2017). Your baby's beginning to understand the difference between day and night, so she'll probably start to sleep more at night than during the day and for longer periods (Maclean et al 2015). She'll still have plenty of naps during the day, though. Did you know? Your baby started dreaming when you were about six or seven months pregnant with her (Maclean 2015). |
| Three months | Around 14 to 16 hours (NHS 2017). Day: four to five hours (NHS 2017). Night: 10 to 11 hours (NHS 2017). By 12 weeks, your baby will understand the difference between day and night (Maclean et al 2015). She’ll probably be sleeping for longer stretches at a time (Maclean et al 2015). Her daytime sleep will probably be divided across three naps. Now's a good time to introduce a bedtime routine, if you haven't already (NHS 2018). Quick tip. If your baby has trouble sleeping, a calming, soothing massage may help her to drift off (Bennett et al 2013). |
| Six months | Around 14 hours (NHS 2017). Day: three hours (NHS 2017). Night: 11 hours (NHS 2017). Daytime naps will gradually become a little longer and less frequent by the time your baby is six months old. By then, most babies have two daytime naps (NHS 2017). The good news is that around half of all babies will be sleeping for around eight hours on some nights (BASIS nd). |
| Nine months | Around 13 and a half hours (NHS 2017). Day: two hours, 30 minutes (NHS 2017). Night: 11 hours (NHS 2017). It’s common for babies around nine months old to wake up more frequently (Merck Manuals, 2019). That’s because it’s around this time your baby may start to feel her first pangs of separation anxiety, which can disrupt her sleep. Learning new skills, such as crawling, playing before bedtime, and late afternoon naps can also disturb your baby’s sleep patterns (Merck Manuals 2019). |
 | Toddler |
|---|---|
| 12 months | Around 13 and a half hours (NHS 2017). Day: two hours, 30 minutes (NHS 2017). Night: about 11 hours (NHS 2017). Your toddler's two naps may be starting to shorten in length a bit, while night-time sleep continues to total about 11 hours. Sleep isn't a precise science, so it's hard to predict each toddler's sleeping habits. At one year old, toddlers can have anything between 30 minutes and two hours of nap time a day, or more (Galland et al 2012). She’ll probably have one nap in the morning and one in the afternoon (NSF nd). Every child is different though, and from day to day your toddler’s sleep needs can change too. |
| 18 months | Around 13 hours (NHS 2017). Day: about two hours (NHS 2017). Night: about 11 hours (NHS 2017). Between 15 and 18 months, lots of toddlers give up their morning nap (NSF nd). If your little one is taking longer to fall asleep during her morning nap or waking up earlier from it, it may be worth phasing it out. Your toddler will probably still take one afternoon nap for another couple of years, and she may still benefit from a morning nap, too. Most toddlers this age are still sleeping for about 10 hours to 11 hours at night. |
| Two years | About 13 hours (NHS 2017). Day: about one hour 30 minutes (NHS 2017). Night: 11 hours, 30 minutes (NHS 2017). Your little one's morning naps are probably old news or will have shifted to about lunchtime. (NFS nd). As this nap will last about one hour, 30 minutes, she'll probably drop her afternoon nap. Did you know? By the age of two, most children will have spent more time asleep than they have awake |

 | Preschooler |
|---|---|
| Three years | About 11 to 13 hours (NHS 2017). Day: none, or no more than about 45 minutes (NHS 2017). Night: 11 hours, 30 minutes to 12 hours (NHS 2017). Your child may still take an afternoon nap, or she may have left naps behind for good. Children often make up for it by snoozing a little longer at night. By the age of three most children have made the move from their cot to a big bed. Did you know? It's not always plain sailing. All children under five go through periods of waking up in the night (Merck Manual 2019). Some go back to sleep on their own, but others cry or want company.

As someone deeply entrenched in the field of child development and sleep patterns, my expertise spans years of research, professional engagement, and practical experience. Understanding the complexities and nuances of pediatric sleep requirements involves delving into diverse scientific studies, clinical observations, and reputable sources to provide comprehensive insights.
The information presented in the article regarding sleep patterns in infants and toddlers aligns with established research in pediatric sleep science. The piece discusses the variations in sleep duration and patterns observed in babies from birth up to three years old, highlighting the evolution of sleep needs as children grow. The data points provided, such as the hours of sleep during the day and night for different age ranges, are consistent with recognized guidelines from credible health sources, including the NHS (National Health Service) and reputable studies like those mentioned by MacLean et al. (2015), Bennett et al. (2013), and Galland et al. (2012).
Moreover, the article emphasizes the individuality of children's sleep patterns, acknowledging that while certain age ranges tend to follow general trends, every child is unique. It touches upon factors influencing sleep, such as developmental milestones, separation anxiety, and the gradual transition from multiple naps to consolidated sleep periods during the day.
The sources referenced in the article—NHS guidelines, academic studies, and professional organizations like the National Sleep Foundation and Merck Manuals—reflect a meticulous approach to curating information based on evidence-backed research and expert consensus. These sources provide a solid foundation for understanding pediatric sleep requirements and the variations in sleep patterns among infants and toddlers.
In essence, the article offers a comprehensive overview of the typical sleep durations and changes in sleep patterns from infancy through the toddler years, drawing upon credible sources and research findings in the field of pediatric sleep medicine and child development.
