Well, I'm at my whits end here. My LO is 6 weeks old and I'm scheduled to go back to work in a week and a half. She seems to have her days and nights mixed up and I just don't know what to do to fix it. Last night she didn't seem to sleep more than 45 mins at a time and there is NO way I can go to work having been up all night. Not only that, she wants to nurse constantly. Could I be having milk supply issues and not satisfying her?? She's having more than 8 wet/dirty diapers a day, so I just don't know. I just can't survive on no sleep.
