My almost 6 week old literally puts up the biggest fight ever at bedtime. I'll feed her, lotion her up, put a fresh diaper and pajamas on her, put her in a bassinet that automatically sways and plays light music, and she just fights it for hours. I'll put her in my arms and she'll fall right asleep. I'll put her right back in her bassinet and she's suddenly whining and crying again. I'm sleep deprived, I find myself crying a lot, I don't understand what I'm doing wrong. Any advice would be greatly appreciated because I'm losing my mind.
