I'm going to join this one, but my DD is only 16 months, not 18. She is getting her canines now, I can see the points, along with some molars (not the 2 year ones). And is just getting past a dreadful cold. Anyway, are all your LOs on this thread 18 mo? Because what we're going through is EXACTLY what I'm reading here, and we're not even 16 months (15.5). I'm wondering if she's just hitting this early, because her teeth are early, and I still have genuine sleep regression to look forward too, or what. I've tried APOP, WI/WO, no dice...still only 1/2 hr nap. I medicate for her teeth. Right now she's at least calm in her crib, and I'm leaving her until the normal time I'd get her up, but she woke after half an hour, screaming, wanted to pee (did that), wanted to eat (gave her a snack in the dark, sitting and rocking). At the moment, if I get her to bed by 6, she'll sleep until 7 and make up the time...just wish she'd take her nap instead!!!!
