Colicky Baby

Meaghan • Mommy to Ainslee - Our sweet, little, IVF miracle baby. Born March 2016!
My sweet girl is 3 weeks old and has been pretty colicky for the last two weeks. The doctor did an ultrasound and put her on Ranitidine for reflux. This has helped with the projectile spit ups but her tummy still sounds awful and she screams in pain after feeding. I've changed to a pretty bland diet and we've tried gas drops and gripe water. We have no idea what to do to help her and we are miserable. On top of that my production has slowed down. Any advice appreciated.
