i have never woken any of mine either for any feeds,but i am lucky enough with all of the others that they just slept through and that was it....
Dominic however 8-[ is another story entirely...he goes to bed about 7pm now,and will wake himself for a feed about 10-11.30pm....i have to say i like it because it means he will sleep right through to 8 am in the morning usually,only because he will drink a full 150-200mls though,which he wont drink before he goes to bed earlier as he is too fussy....
I say go with what you want to do....
Dommie didnt go to bed til 10pm last night and slept right through til 8am this morning,so maybe the dream feeds are the way to teach them good sleeping hours,but then having said that i dont think i would be comfortable waking Dominic,but its ok if he wakes himself.....
(if anything made sense out of that it is good,because looking at it doesnt make much sense to me!!)
