My daughter had colic. It was due to a milk allergy. Try Nutramigin formula. It is expensive but helps. She also had acid reflux and was give Zantax. That also helped but did not eliminate her colic. Her colic did stop after four months. However be leary of giving your baby cereal to soon. I gave her cereal at four months and the crying came back. The doctor said she could not digest. So I think that was another problem that contributed to her colic. So I took her off the cereal at four months and she was fine after two days. I introduced the cereal at six months in her bottle. I thinned the cereal out, very thin, and put it in her bottle. At first once a day, then twice, morning and bedtime. I also put her in the swing at night to sleep when she had the colic. IT HELPED! Prior to that I was up with her half the night or more. Try these things, and remember it does end and you will have a beautiful child! Good Luck!
