My 7 week old will not go to sleep or stay asleep in a quiet room. She’ll sleep through anything during the day - talking, the tv, even the vacuum running. But at night she will only sleep if music is playing. We currently have a mobile on her crib that plays for 15 minutes at a time, so I get up and turn it back on every 15 minutes. If I don’t turn it back on she usually wakes back up and gets a little fussy. Does anybody have a music machine or anything that plays for longer periods you would recommend I get? If I can’t find anything like that I’m considering buying a cheap radio to sit next to her crib with some lullaby cds.
