Baby is almost 5 weeks old. Still waking up at least every 2-2.5 hours to nurse. I had a meltdown last night when he woke up starving only 45 minutes after he went down from the previous session. When do they start going longer between night feedings? Is there anything I can do to speed it up? I mean, I knew I would be getting up a lot at night but I have yet to sleep more than 2 consecutive hours since he was born, and there's NO end in sight! I'm going back to work in about a month and I'm really nervous about it, seeing as I need to use my brain to do my job. Any advice?
