Our previously champion sleeper started pretty suddenly waking every 2-3 hours. This has been going on since right around 6 months, so for the last month, DH and I are zombies. She goes down at 830 and wakes at midnight, 130, 330, and then 6ish. I'm losing my mind. She has 3 teeth, but they all had erupted before this sleep issue started. I don't really see signs of tooth number 4 yet. She's slightly congested, but only for the last couple days.
Anyone have any brilliant sleep tricks? Or at least commiseration?
