Hello everyone! We're on Gavage, trying to give her a mixture so she could take a break every now and then, but she doesn't want to. She starts crying or holds the bottle in her mouth and throws up, and even refuses to drink from another bottle. I heard that after a bottle, the baby doesn't want the breast, and my baby doesn't want the bottle. In a little over a half a month we need to introduce solids, I'm afraid she will also throw it up. Has anyone experienced this and what did they do?
