Wake Windows & Sleep Cycles, Oh My

What is a sleep regression?

A sleep regression is a time where your baby's sleep patterns change and are disrupted, usually due to different developmental milestones occurring. They can last anywhere from a few days to a

few weeks.

When do these regressions typically occur & why?

4 months - baby is transitioning from newborn sleep to mature, "adult" sleep which adds two more sleep cycles to their sleep time. This is infamously known as the most difficult regression.

8 months - this usually happens between 8-10 months because baby is learning so much. During this age they learn to sit up, crawl, pull to stand and are absorbing language like crazy! Babies typically want to practice these skills all the time, even in their crib.

12 months - the least common and stressful sleep regression (usually). You will likely start seeing your little one protesting their second nap.

18 months - this regression can be attributed to teething (the dreaded molars), their new found independence or separation anxiety.

24 months - the 2 year regression can be a tricky one. So many things are changing such as, potty training, wake periods growing longer, and nightmares/terrors are also likely to begin at this age.

It is important to remember that all babies are different. Some may hit these milestones earlier and some a little later and that is totally ok!!!

What can you do to help during a sleep get things back on track during a regression?

Stay consistent. Consistency and predictability are key in

maintaining sleep habit and getting back on track during a

regression As difficult as it can be, try not to deviate

from your structure and routine.

Added comfort. You may need to assist your little one in

falling asleep more than usual. That is ok! Comfort them

through this difficult time.

Adjust bedtime. Naps can be particularly challenging during

a deep regression. If naps are shorter and less frequent

consider bumping up bedtime to 30-60 minutes earlier.

Add in an additional daytime feeding. Developmental

milestones usually also mean physical growth. Your little

one may be hungrier than usual. Offer an additional feeding or

snack throughout the day.

Practice, practice, practice. Whatever your little

ones newest skill practice as much as possible during the day.

This will make them less inclined to need to practice during sleep time.
