Why Does My Baby Have Days And Nights Mixed Up?

My baby seems to have his days and nights reversed. How do I get him back on track?


It is not uncommon for newborns to have their days and nights mixed up, meaning that they sleep more during the day than during the night. At two to three weeks of age, you can start signalling to your baby that nighttime is for sleeping and not for playing. For example, keep the lights dim and noise to a minimum during night time feeds and diaper changes.

If your baby is more active during the night, try increasing his wakeful time during the day and expose him to daytime light, especially early morning natural light. Nighttime sleep starts to consolidate between six and 12 weeks and by two months of age many babies naturally start sleeping for longer periods at night. By two months, I would limit daytime sleep to five hours and work towards getting nine to 10 hours of sleep at night, including night feeds.
