Welcome to your child’s first official sleep regression. This regression has a lot of meaning and there are a number of reasons for it! Knowing those reasons can help you improve your child’s sleep so that you can come through the other side of this with a well-rested baby!
First, let’s look back. The first four months may have been filled with irregular sleep patterns and sleep may have often been unorganized. This happens because infants younger than 4 months of age (adjusted to the due date if the baby was born early), have immature sleep biology. Your baby’s interval clock (circadian rhythms) and sleep hormone (melatonin) were not yet fully intact.
Reasons for the 4 Month Sleep Regression
At 4 months old, your baby will begin to have more defined light and deep sleep cycles, just like we do. When your child is transitioning between sleep cycles, they are more likely to wake and not transition to the next sleep cycle. This transition process from one sleep cycle to the next can be hard for little ones who can’t put themselves back to sleep. This is often the reason for short naps and multiple night wakings.
Your baby may need an adjustment in their sleep schedule. If your baby is not sleeping at the right time or going to bed too late, there is another hormone that has matured and that is called cortisol. Cortisol is a stimulant that will give your overtired baby the message to stay awake.
Also, where your baby sleeps can cause sleep disruptions. Before 4 months of age, your baby may have been able to sleep anywhere. A new baby can sleep on the go and even in a noisy and busy environment. However, due to the development of the circadian rhythms, your little one will wake much easier when things are busy, noisy, or bright.
Another cause of the 4 months sleep regression is skill building! If your baby is working on the skill of rolling, you will see sleep disruptions. Who wants to sleep when they can practice this amazing new game? This can be an exciting and frustrating time for your baby. Often babies learn to roll one way first, but then get stuck, which can be frustrating, and they will “call” for you to help them out.
What To Do to Get Through The 4-Month Regression
Now that we looked at what the 4-month sleep regression is, here are tips to help your baby become a well-rested baby and get Backtozzzs. It is the perfect time to start your child on a path to healthy sleep habits.
1. If you have not yet done so, begin to offer naps and night sleep in a consistent and conducive sleep environment. Offering sleep in the same place each time will help your baby become comfortable in their sleep space. Now that your little one’s melatonin is intact, darkness will help support this hormone. Darkness tells the body that it is time to sleep. I also recommend using a sound machine to keep outside noise outside. This will be helpful when your child is transitioning sleep cycles and going into lighter stages of sleep.
2. Begin to offer a soothing and consistent sleep routine before each nap and bedtime. This will help your child learn what to expect and what is coming next. This is a wonderful cue that will help your child’s mind and body relax and prepare for sleep.
3. It might be time to adjust your little one’s sleep schedule. Instead of offering sleep on a wake-window schedule, start to offer your baby sleep at consistent times each day. It is also important to move bedtime earlier. Early bedtime is a key ingredient in helping your baby stay well-rested. At this age, you are aiming for 3 naps a day (2 long naps and a short cat nap) with an early bedtime.
4. If you are ready, you can begin to teach your little on to fall asleep unassisted through sleep training. Sleep training is where you use your sleep routine to relax your baby, but not to put your baby to sleep. Instead, you put your baby in the crib awake. From there, you use a sleep training method to respond. There are a number of sleeping training methods to choose from. I suggest picking one with which you are most comfortable. The key ingredient in sleep training is consistency! So, choice the method you feel you can be consistent with.
5. If your child is working on the skill of rolling, do a lot of floor and tummy time to practice this skill! The sooner they master this skill, the sooner they will be able to make themselves comfortable in their safe sleep space.
Even though this is an exhausting time. The 4-month regression is actually good news. Now that your child has developed circadian rhythms, you can now start to teach the skill of independent sleep if that is something with which you are comfortable. If so, a sleep plan can be put in place that will allow for healthy and restorative sleep!
