Sometimes I can still hear my daughter's cries in my ears, and we sleep trained her using the cry it out method well over a year ago. I vividly remember how it felt to wonder if it had been two minutes or 20 (it always felt like 20, but was always two), or whether it would ever end. I vividly remember the giant sigh of relief we both exhaled when the house went silent. I definitely remember the things you learn about your partner when you cry it out because, well, some lessons you just never forget.
I suppose I should have expected that my husband and I would have such different reactions to crying it out, despite it being a decision we made together. He's a stick-to-the-plan type, with a fierce competitive streak that has served him well in basketball games but gets awfully annoying in real life situations.
We quickly learned that, without my husband there to give me regular pep talks and reiterate the plan, I would have melted into a puddle the second the first peep escaped my daughter's mouth. While she was crying (which admittedly didn't last very long at all) I wondered if my husband's heart was made of stone. However, when all was quiet after a few minutes of fussing, I realized he's simply programmed to be entirely more optimistic than I am. I also learned the following things about my partner during this time period, and I have a feeling if you're crying it out with a "buddy," you'll figure out a few interesting things about them, too.
