Why this works
The 4-month regression is the most common reason parents search for sleep help. One day your baby is sleeping in 3-hour stretches. The next day, they're waking every 45 minutes all night. Nothing you did before works anymore. You're not doing anything wrong — your baby's brain just permanently changed.
At around 3-4 months, babies' sleep architecture matures to resemble adult sleep. They now cycle through light and deep sleep stages, and they briefly wake at the end of each cycle. The problem is they haven't yet learned how to connect those cycles independently — so every time they surface from a light sleep stage, they need you to help them back down.
The 3-4 Month Guide gives you two things: first, a clear explanation of what's happening so you stop blaming yourself, and second, a practical plan for rebuilding sleep without cry-it-out. The plan centers on four pillars: the right sleep environment, age-appropriate wake windows, a consistent bedtime routine, and a gentle introduction to self-settling that doesn't involve leaving your baby to cry alone.
Most families who follow the guide see meaningful improvement within 7-10 nights. Not perfection — this age still needs 1-2 night feeds — but the difference between waking every 45 minutes and waking twice a night is life-changing when you're in the thick of it.
