Making it through the night

Being a mom has been great. I love Collins Avery so much, she is the joy of my life. She is growing so fast, I cannot believe that she is already 3 months old. We have been trying to get a routine set, but she has been putting up a fight. She was sleeping 7 hours a night now she's back to waking up every 2. I always thought I was going to be a though mom and let her cry it out, but I am such a sucker. I don't last five minutes, and I have to pick her up. But I need to though it out and let her cry. I know she ate enough during the day that she should not be waking up often at night. We will see how tonight goes, I have decided to just out the pacifier in her mouth if she starts crying. Wish me luck and hope I make it without picking her up.
