14-15 Month Sleep Regression

Are you noticing some changes in sleep around 14-15 months? You might be seeing what some may call the 14-15 month sleep regression. Let’s talk about what this might look like and how to help your little one if sleep is challenging.

Is there a sleep regression at 14 or 15 months? #

There can be a sleep regression at this age! It’s a less common sleep regression, but families can see challenges in sleep around 14-15 months. Perhaps your 14 month old is suddenly waking up at night, your 15 month old is fighting naps, or your 16 month old is now waking earlier and earlier. If you are seeing changes in sleep around 14-15 months, you may be experiencing a sleep regression. 

What causes a sleep regression at 14 or 15 months?#

Sleep regressions can happen at any age and are often tied to developmental progressions. The most common ages to see sleep regressions are at 4 months, 8-10 months, 12 months, 18 months, and 2 years. However, any time a baby’s brain and body are growing physically, mentally, and emotionally, sleep can be impacted. 

Let’s talk about reasons you may see a sleep regression around 14 or 15 months:

Developmental progression: Around 14-15 months, your toddler may be taking a few steps,  walking independently, or even climbing on furniture or stairs. You may notice your 14 or 15 month old is trying to be more independent and starting to imitate your actions, like “cleaning” up or trying to put on their own socks. Sleep may look different while your 14-15 month old is learning these new skills; their brains and bodies are working hard!

Separation Anxiety: As your little one becomes more independent and mobile, you may find that they actually need more reassurance that you’re nearby. Your presence gives them confidence to explore their world more freely. Your toddler may also better understand the concept of object permanence. This combination often results in a peak in separation anxiety.

Big transitions: Transitions like switching from breastmilk or formula, transitioning from bottle to cup, weaning from nursing, moving to a new room at daycare, or weaning the pacifier may happen around 14-15 months. These changes can present new sleep challenges as your baby adjusts to new expectations.
