This time of year of course everything shifts later. Bedtime moves one hour later than normal. It is generally far easier to fall asleep one hour after your normal bedtime, than one hour prior (such as in spring).
For babies around 8 months plus, they can’t adjust with such a long awake time. Shifting their schedule every few days by 15 minutes is an effective gradual route. Focusing heavy on their routine should be soothing, using tools like darkness and winding their mind and body down with sleep stories, such as the app Moshi Twilight.
Side note: when using sleep stories electronically, place the device under the covers or flat down and away from eye sight so the screen isn’t visible. The blue light that emits from the screen is what suppresses our sleep hormone.
Here’s how you can adjust bedtime a few days before the time change:
Use 15 minute incremental adjustments. Bedtime becomes 7:00, 7:15, 7:30, 8:00 PM, which by the post-DST clock is the “new” 7:00 PM. The same happens in the morning – 6:00, 6:15, 6:30, 7:00 AM (try to leave them in bed until your target wake-time). In four days, your child has adjusted to the new daylight savings.
For older children, this is fun because they get to go to bed an hour later. So if your baby previously slept from 7:00 PM – 6:00 AM, they’re now going to bed at 7:00 PM (clock time, 8:00 PM body time) and sleeping till 5:00 AM (clock time, 6:00 AM body time) for a net loss of 1 hour. It can take a few days to adjust to this shift but most do fairly readily within a week.
