As a sleep consultant, I have found that the word regression pops up in nearly every imaginable circumstance. If a baby has been sleeping well for a week or months and suddenly hits a hiccup, it receives the "R" label. Some believe there's a regression at eight months or a year. I have some news for you: the dreaded four-month regression is absolutely REAL, and it's PERMANENT.
