Your baby had been sleeping so well, you honestly thought you’d cracked it. You even wrote down the exact 10-step routine that worked like magic… and then suddenly, everything changed. Now they’re up every hour and naps last about 17 minutes.

Sleep regressions, or progressions (not that calling it that, makes you any less sleep deprived) as I like to call them, are usually tied to big developmental leaps and as a result, sleep just goes a bit spicy. 

Inside, you’ll learn the key signs to look out for, what’s really causing the sudden changes in your baby’s sleep, and what’s actually happening beneath the surface.
