12 and 13 Month Sleep Regression — Emerging Toddler Skills Might Be to Blame

As your baby approaches 12 months, it’s time to talk about sleep regressions — AGAIN! Do you sometimes wonder if your baby’s sleep regressions will ever end? Will you EVER be able to count on a good night’s sleep for you and your child? You know you’re facing a 12 month sleep regression when your child is experiencing:

  • Increased fussiness
  • Multiple night wakings
  • Fewer naps or short “disaster naps”
  • Changes in appetite

Developmental Milestones Bring Sleep Regressions

Let’s face it. Sleep disruptions come with any major change in your baby’s life. Travel, teething, a cold, moving to a new home — even a big day at a new playground can all disrupt your child’s ability to calmly go to sleep and stay asleep for the night. At 12 months, major developmental changes are happening in your baby’s body and brain. Their internal world is expanding how they see and interact with their external world and these changes are exciting and sometimes a little overwhelming for them. At 12 months your baby is either doing or getting ready to do these things:

  • Say a few words, including ‘mama’ and ‘dada’
  • Stand on their own
  • Take a few steps, holding on to something or on their own

12 and 13 month sleep regression Naps are the First to Go

The most common problem parents see at the 12 month sleep regression is a complete disruption of babies’ naps. Thanks to all of the excitement of their developmental progress, babies at this age will FIGHT their naps. It may even look like they are transitioning to only needing one nap a day. Don’t be fooled! It’s a temporary phase, just like the sleep regression itself.

The typical age for babies to drop to one nap instead of two per day is between 14 and 15 months. At 12 months, keep offering two naps and do your best to help your child settle into sleep by having a regular nap time and a soothing nap routine. Use The Shuffle strategies to offer your child some support and comfort as they fall asleep or when they wake early.

Extra Support Helps

Watching your baby struggle with sleep is hard. Losing sleep yourself is hard, too. Remember that just like the 4 month, 7 month, and 9 month sleep regressions, this is a temporary phase. It’s also a phase where your baby may need extra support while they weather the frustration and excitement of learning new skills. You can help them get through the sleep regression faster and more smoothly:

  • Offer comfort and reassurance — extra hugs and cuddles help
  • Feed your baby more frequently if he seems extra hungry — growth spurts can be part of a sleep regression
  • Avoid over-tiredness — stick to your nap routine and consider an earlier bedtime if she seems extra tired or extra fussy in the evening
  • Avoid old (or new!) bad habits — don’t resort to rocking or feeding your baby to sleep. Stay nearby at bedtime and use The Shuffle to comfort and reassure him

It’s hard to believe now when nights and naps are undependable but with consistency and some good sleep coaching you’ll soon be out of the woods – usually in no more than 2-3 weeks.

My name is Kim West, and I’m the mother of two beautiful girls, a Licensed Clinical Social Worker who has been a practicing child and family therapist for more than 21 years, and the creator of the original gentle, proven method to get a good night’s sleep for you and your child. 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!
