Husband ruined my kids perfect sleep habits desperate for advice

5 weeks old and she had been sleeping in her bassinet on her own wonderfully. Now she (thanks to my husbands coddling ways)  won't sleep in bassinet anymore. She won't sleep even in her swing she refuses to sleep anywhere other than our arms. I've tried everything the Internet tells me to do! The crib has me scent all over it with milky breast pads under her thing sheet. I tried swaddling I put her in the bassinet when she is knocked out milk drunk dead asleep and she wakes herself up and cries! I don't know what else to do! I'm so desperate! I hate cosleeping it scares the shit out of me.
