My wife has done the same thing at times. It seems to help her enough and I know what she means so I don't get upset.Sometimes she needed to say, out loud and without judgment, "I hate being a mom (right now). This change in my life sucks and is not at all what I was expecting." Our culture might recoil at those statements, but having a kid is a major (MAJOR) life change and it's not always what it's cracked up to be.
