Are you facing sleep challenges with your little one? Explore our complete guide on sleep regressions during your baby’s first year, which includes insights on the three-month, six-month, seven-month, eight-month, nine-month, and twelve-month sleep regressions.

While some milestones in your baby’s first year, like their first roll or sitting up, fill you with joy, others, such as the four-month sleep regression, can be daunting. You may have heard from fellow parents about this tough phase or be caught off guard by your baby’s sudden change in sleep patterns. If your baby is four or five months old and hasn’t exhibited signs of sleep regression, you might be concerned. Rest assured, they are likely just fine. Here’s a breakdown of the four-month sleep regression, along with tips to help weary parents navigate this phase.

Understanding Sleep Regression

Sleep regression generally refers to a period of two to six weeks when a baby or toddler who once followed a regular sleep routine suddenly struggles to maintain that schedule. This may manifest as frequent nighttime awakenings, shorter naps, or outright refusal to nap—leaving exhausted parents feeling frustrated as they try to regain their normal sleep habits.

The concept of sleep regression has been explored in developmental psychology since the 1940s. However, despite decades of research, experts still grapple with understanding why and when these regressions occur. While many resources outline specific “stages” of sleep regression, it’s crucial for parents to remember that every baby’s experience is unique. If your child’s sleep patterns don’t align with these timelines, it’s typically not a cause for concern. Always consult your pediatrician if you have questions.

What to Expect During the 4-Month Sleep Regression

The first sleep regression phase typically emerges between three and five months, commonly referred to as the “four-month sleep regression.” In addition to disrupted sleep, signs may include increased fussiness, waking multiple times at night, shorter naps, and altered appetite. This regression often coincides with a baby transitioning from their newborn sleep habits—though the exact cause remains unknown.

During this challenging phase, your baby’s brain is actually undergoing significant development, marked by growth spurts and the acquisition of new skills like sitting up or rolling over.

Tips for Navigating the 4-Month Sleep Regression

While it’s natural to feel frustrated when your baby’s sleep routine is disrupted, it’s essential to remember that this phase is temporary. Here are some strategies to manage the four-month sleep regression:

  1. Ensure your baby is well-fed before bedtime.
  2. Keep the nursery dark to promote better sleep.
  3. Establish a consistent bedtime routine, like changing into pajamas before sleep.
  4. Wait a few moments before tending to your baby if they cry at night; they may settle back to sleep on their own.
  5. Watch for signs of sleepiness. Even if your baby seems resistant to sleep, recognizing early signs of drowsiness can help you put them down before they become overtired.

Patience is key during this parenting phase. Knowing what to expect can help ease the burden.

Sample Sleep Schedule for a 4-Month-Old

To combat sleep regression, creating a structured sleep schedule can be beneficial. Here’s an example you can adjust to fit your baby’s needs:

  • 8:00 a.m. – Wake up
  • 9:45 a.m. – Nap
  • 11:45 a.m. – Playtime
  • 1:30 p.m. – Nap
  • 3:30 p.m. – Playtime and tummy time
  • 5:30 p.m. – Nap
  • 6:00 p.m. – Baby exercise
  • 7:30 p.m. – Begin bedtime routine
  • 8:00 p.m. – Sleep
