When my son was born I called my mom and said "I've ruined my beautiful marriage." I might have also said, "I'm not sure I want to be a mom." It was so hard. He was so hard. I was so tired. Things turned around for us when I read something that said when possible have both parents get up at night with the baby. Though it seems counterproductive (your husband really could be sleeping, he has to go to work, only you can feed the baby) it's actually a great way to help you reconnect, like you're both in this s*^# show together.
