She won't sleep in her cot, she won't sleep in her car seat, she won't sleep in her pram. She will only sleep if she's held and even then not for very long. She is exhausted because she wakes up because she's unsettled, not because she's well rested. I don't know what to do. She cries and cries and cries because she's so tired. She gets herself so worked up that she won't feed and so she just won't settle. I have a sling but she won't even go to sleep in that for me. Please help me. My baby is becoming really unhappy because every waking minute she is exhausted.
