Meg, she's been having the issues with crying as well? Honestly mate, I would see a chiropractor or Gp or someone soon to have her assessed. I found chiro's to be super helpful with pain, and your family GP should have this on record just for future sake. Matilda was diagnosed with reflux at 6 weeks and hers was diagnosed because she had burns down the back of her throat. its worrying, but what she is doing seems alot like what Matilda did as a bub.
