My baby won't keep any formula down. I breast feed and I could tell that baby wasn't getting enough. He just wasn't content after his feedings. So the doctor advised that I give him half an ounce of formula after every feeding. Yet, as soon as I give him the formula, he throws EVERYTHING up. He becomes hungry again and the process repeats untill he becomes to tired to stay away to feed. I've tried every formula out there but nothing seams to work. Please help me! What can I do? I feel like a horrible mom. 😟😰
