Sleep Schedule

    4 Month Old Sleep Schedule

    The 4-month sleep regression is one of the most challenging phases for parents. Your baby's sleep cycles are permanently changing, and they now experience lighter sleep phases where they can easily wake. The good news? This regression ends, and the new sleep architecture is here to stay. Hang in there!

    Common Challenges at 4 Months

    • The 4-month sleep regression — baby's sleep cycles permanently mature
    • Previously good sleepers may suddenly wake frequently
    • Short naps and early morning wakes become common

    Tips for Success

    • The "regression" is actually a progression — baby's brain is developing adult-like sleep cycles
    • Keep routines consistent even when sleep feels chaotic
    • An earlier bedtime (even 6:30pm) can help with overtiredness
    • This is often when many families consider gentle sleep training methods
