When my son was a newborn he would always wail after we fed him. I began to think his formula wasn’t sitting well in his tummy so I did some research. After reading reviews, I decided to give this one a try and I’m so glad I did. After his very first bottle with this formula, he went to bed easily and slept until it was time to eat again. I’m not sure what was in his other formula that was giving him issues but I do know this formula made a world of difference, instantly. My son is now 10 months old and continues to use this formula with no issues.
