The second day in the hospital. Why does she only sleep on my hands? I didn't sleep all night because of this and during the day. Only when I put her where she should be, it starts crying. And calms down only on my hands. What do I do about it? And it also hangs on her chest. We thought that there was little milk, we gave her formula, she didn't eat it, and then she even threw up.
