We have a baby who is 3 weeks old (when I write this). She is very nice and sleeps very well during the day, however it seems to be difficult for her during the night. The problem is that, even she is sleeping, she makes some noise as if she had nightmares. (This happens each 1 hour during the night.) When we try to hold her and swing her, she becomes calm as usual, but when we put her back to her bed, she feels angry and does not want to sleep anymore.
Someone can help us? Thanks in advance!
