Daytime/nighttime confusion

Katie

Seems our little one has decided to be nocturnal. After her 1am feeding she’s generally up, alert, feeding or crying until at least 6am. Today I started trying to train her, which I know will take time, but I was wondering if anyone had any successes or tips they can share. Also, she’s 4 weeks (born 3 weeks early), is it too early to start? Thanks!
