My daughter is about a month and a half old and she was sleeping great. But now she isn’t she takes 15-30 mins naps about 4 time during the day. Then at night she sleep 4 hours then is awake then falls asleep for another 2 hours. I feel awful because I know she’s tired but she just won’t sleep. Any recommendations? We have tried swaddling and baths and holding her. But she would sleep for hours on us but we can’t be doing that. So any reason why she is doing this
