oooohhhh... the memories. My daughter had Colic... Something I do not wish on any mom or baby. I had to shake her and bounce her and walk her for HOURS at a time. Finally, what helped the most, was putting her in a swing, and I had an older one that you had to wind every 7 minutes. I would get up to her wimpering about every 8 minutes through the night, but she would sleep in that swing. Her little tummy just wouldn't settle if she was still. We good days, bad days, and there was ALWAYS a certian time of day that she was worse than others.
I'm not diagnosing... I'm just suggesting to try and bounce your baby a little more, try and take her for rides, put her in her carseat on the dryer while it's going... There were times that I'd bounce mine so much I thought I was hurting her.... that wasn't so, she'd start crying if I stopped. Her belches would be SO STINKY when they'd finally come out. As Colic is just a bad gas buildup, there wasn't an issue with diaper filling - she did that VERY WELL! haha
