Sleep Regressions at All Ages: Just a Phase?

We’ve all been there. Baby has been peacefully sleeping through the night, and, consequently, so is everyone else. Hooray! And then, out of the blue, your sweet baby is up at all hours, wanting to be soothed, fed, and crying. What happened? Many refer to these short episodes as a Sleep Regression.

When Will My Baby’s Sleep Regression End?

If you’re asking yourself this question, chances are that you’ve been short on sleep, and so has your very cranky, sleep-fighting baby. Sleep regressions at all ages are difficult, but thankfully most children (not all, but most) don’t experience every sleep regression. If they did, no one would sleep during the first two years!

4 Month Sleep Regression

You’ve got the schedule down. Baby is FINALLY sleeping more… and then, WHAM! Suddenly she’s not. Welcome to what is commonly referred to as the 4 month sleep regression. Some may refer to this phase as increased wakefulness, but it all amounts to the same thing — you and baby have newly found your groove, and now baby just isn’t acting like herself.

Here’s some more about the 4 month sleep regression:

Pre-Toddler Sleep Regression

I’m not going to claim that all babies experience a sleep regression (or two), but most do. And if there is one sleep regression period that seems to be abundantly common, it’s when babies learn to crawl and/or pull themselves to a standing position. This is a huge step in their gross motor development, and opens an entirely unexplored world. Of course they don’t want to sleep, and therefore, parents experience some very common baby sleep problems.

The pre-toddler sleep regression happens somewhere around 9 months-old.

The 18 Month Sleep Regression

You were sleeping peacefully…and then you hear your toddler. He’s not just rustling around resettling. He’s screaming mad. Literally. As you drag yourself out of bed, you wonder to yourself what’s wrong? What could be causing your toddler sleep problems? Could this be two-year molars? An ear infection? Is he gassy from eating too much broccoli at dinner? Is his newfound walking (or running!) causing this?

The answer: It could truly be any of the above. But it could also be yet another sleep regression.

The 2-Year Sleep Regression

Many parents breathe a sigh of relief once their child hits the toddler years. But then you’re dealing with molars, budding independence, and (for some) potty training. Logically, we think that development keeps moving forward, but when it comes to two-year-olds, you’ll notice that there’s a bit of backsliding as they learn new skills and grow up a bit, which includes the potential for another sleep regression.

My sleep journey began when I started experimenting with gently shaping my daughter’s sleep by not following the conventional wisdom at the time. After having success (and then more success with my second daughter!), I began helping family and friends and my step-by-step method spread like wildfire, exactly like an excellent night of sleep for a tired parent should!
