oh my, purpleprincess; i could have written your post here.
my son, now 21 months, has had on and off sleep problems. same thing, frequent waking during the night, loud talking, cot-kicking, hitting the wall, shouting for us, but NOT crying.
this started when he was 18 months old. and we tried lessening his daytime nap to an hour, making his bedtime later. he gets plenty of exercise and out and about time, so none of these things helped. (i dont want to discourage you!)
you could offer a small snack before bedtime. and stick to a bedtime routine as much as you can.
my ds has woken the last 2 nights but before that he slept thru (7am-5.30am) for 6 nights. so its not a constant thing for him either. my hv recommended us to go to a sleep clinic, but im not able to get to it during the times they run it:( maybe ask your hv about a local sleep clinic? also have you had your dd checked out by your GP, just to rule out any possible medical problems? (we did this and my GP said that if it was medical the waking would most likely be nightly)
i empathise. completely. hang in there...
