Hi Naomi - thanks for responding and well done for being out the other side! How long did it take, and what form...?!
Things are pretty all over the shop. All started about 6 weeks ago (she is 18 mo in a few days) when she got bad chicken pox, we went on holiday and we finally (after several months of back and forth) committed to 1 nap only.
The last few weeks have been totally lacking in routine (however hard I try), EWUs, patchy naps and for several weeks taking over an hour to settle at bedtime, and now we've extended her last A, she's settling in 10 minutes but with lots of crying and protesting. Sigh. She's also quite SA (and she's always been clingy) and frankly in the day, she is just manic. Non stop whirlwind. And with 3.5 yo DS, who is a chronic 5.30/6am riser, I'm knackered... Does it sound 18 mo SR-y to you?
