Okay, so I need some good advice right about now. My baby is 3 weeks old and he's starting to get really fussy and not sleep at all during the night, I'm running on about 3 hours sleep, what do you ladies do to help with your exhaustion? I think I'm still adjusting to all this because my whole life, I've been able to just sleep all through the night with no interruptions and now I can't answer I'm trying to not let it take its toll on me. I wish I could nap as much as he does through the day, but as you know, as moms, we still have stuff do get done during the day. When will this start getting better!!?
