K.P.
Hang in there, T.! You are not alone!!
My daughter was colicky for about 10 weeks. She would wince and cry after feedings, which made me very upset and question my parenting abilities. She also would spit-up (but not enough for her pediatrician to be concerned). Around 10 weeks, she had a poopy diaper that had streaks of blood in it. I immediately called the doctor, who said it was an allergy and suggested trying a soy-based formula. Within a few feedings with teh formula, she was a totally different person/baby. I stayed away from cow milk until she was about 18 months and then I slowly introduced it to her system. She's over two years now and she drinks milk just fine.
Also, if it is gas, the pediatrician said gas drops to not work and Tylenol is better.
Colic is tough, so just keep looking for ways to comfort that little one. She appreciates all you do for her. :)
I'll be thinking of you!!
