cramps

Our little Mollie is 3 weeks old today. For over a week now, she's been struggling with colic. I've tried a few things, but I'm starting to think it's just a matter of time for her intestines to adjust. Now I'm really dreading the coming weeks. You just don't get anything done... not even doing laundry or ironing a bit... I'm just comforting her all day long. She also sleeps very little during the day due to the cramps. Are there any moms with experience? How long did it take for your kids??
