hi again janie lee,
my boy has been on the proper day/night cycle since before his first month, so i'm v thankful for that. i only wake up once or twice between midnight and daybreak to nurse him - if he asks for it.
uhm, he's been drinking from one breast at each feed since the start of the 2nd month, although there are occasions when he still wants the other breast, usually because my left breast seems to produce lesser than the right. dunno why. his drinking time ranges from 5 minutes to 20 minutes even on one breast before he is satisfied. the feed before bedtime is usually the longest as i suspect he wants to suck all he can before he surrenders to sleep.
i have bought pacifiers but refused to use them, no matter how tempted i have been. i want him to discover his fingers and i rather him suck on them, then suck on a pacifier, because he can control when he wants to suck his fingers, whereas pacifiers, if used wrongly, may have the negative effect of dumbing him up. well, anyway, i am not confident in using the pacifier during the 'right' situation, so might as well not start on it.
i don't have any special tips to reverse the sleep cycle, but a very effective method is to institute a bedtime routine. after his feed at 6pm, i will start to draw the curtains, dim the lights, put on the same classical cd and keep him in the room after my dinnertime, all the way until he sleeps. and this is regardless of whether he fusses or screams his head off before bedtime (my boy is colicky).
