Do you use any essential oils? I was super exhausted and crazy sore for a few weeks there because my LO would cluster feed for HOURS every evening and into the early morning hours. Then I started putting a dab of lavender essential oil on her swaddling blanket when I'd put her down for bed and she started sleeping better. It seemed like the scent would relax her so she'd sleep better, I'd sleep better (and more), and it even seemed to help with the cluster feeding a bit. And yes, this too shall pass. We're fast approaching 2 months here and LO is now sleeping through the night most nights. (Bedtime is around 9:30-10pm and she gets me up between 4-6am, nurses for an hour and a half, and goes back down for a few more hours.) I'm hoping things stay this good because I go back to work part time next week and my mornings of sleeping til 9-10am will be a thing of the past.
