Welcome Doj. I've been following your thread, too, and wish I could offer more advice/help. We don't have any experience with night terrors, so I don't have any advice to offer there.
Our night wakings have gotten better. Carys slept through the night last night except for one time she cried out, but was able to get back to sleep on her own.
Much better. But...she's still only averaging about 9 hours of sleep at night.
She went to bed later than normal last night (8pm) and woke at 5:15am. Yesterday was really bad trying to get her down for a nap - she kept screaming and screaming. I finally let her fall asleep on me in the rocking chair and she slept an hour and 45 min. - her previously normal nap length.
Sorrry - gotta go. Here she comes...
