like 2 hr long night wakings, last night was just 1.5 hrs.
DD's routine in more or less a nap every 3.5 hrs. roughly
wake 7:30 (usually not this late but with such long night wakings she sleeps a bit longer. we are used to 6am wake up)
nap 11 (we did have a 10:30 set nap time but she is just not tired enough to fall asleep then) I usually wake her after 2hrs nap if she hasn't woken already.
nap 4:30 - 5 I have to get DD from the bus at 4 so she really can't go down before that.
Bed 8pm
Now this is ideal but it's not always this way. Yesterday she had 1 nap, last satruday she had two short naps because of our family outing, and sunday she had a short nap at church in the morning and a 2.5 hr nap in the afternoon )followed by a 11.5hr night where she slept through completely.) We are having these really long night wakings about 2 or 3 nights in a row and then one good night and then back to the grind! This has been going on for about a week and a half now.
Developmental? (I really hope so although past experience tells me this usually happens around birthdays.)
We are working on getting her to go down on her own for bedtime. She is getting to the point where she is annoyed with sh/pat!

She is teething but we keep her medicated when she is in pain and I really don't think the long night wakings are due to pain. perhaps initially but not after 20min once the meds kick in. She has been great over the last 3 days or so where we don't have to medicate her for teething pain during the day and these night wakings are still happening.
When she wakes she is usually WIDE awake! I try literally everything to get her back to sleep but she is just still wide awake!
