Hi Liquid,
I've got the same routine in the back of my mind, and Fraser's fitting it quite well at the mo - but it's not because I'm particularly forcing the issue. The first couple of weeks I just woke him every 3 hours to feed (from start of feed to start of feed), and it went fine. Now he's tending to be more alert, and nap about 1 1/2 hours after he wakes up, so is awake a bit after feeding. I am less stressed about following things to the letter this time though, and maybe that's why it seems to be going better.
Today, for eg he woke up at 6.50, I fed him about 7-8, then he slept again from about 8.30 - 9.50, fed him again on and off from about 10ish, and he's just gone down again for another nap. I guess he'll sleep about 1 1/2 - 2 hours before he's hungry again. Yesterday was a bit different, he woke up and fed about 7.30, then napped from about 9.15 - 11 (I woke him up!), fed again and then napped again about 12.30 - 2.30, fed again and then napped about 3.30 - 5 when I woke him up, gave him a little feed, and tried to keep him awake until bath and bedtime! It all works out in the end, and essentially he's feeding on demand, but his demands seem to be quite structured!
I don't know if it's true of all bf babies, but both mine tend to feed with great big gulps for the first 10 mins or so, then have a break, feed again a little while later, and so on for about an hour at a time. Don't know if this is different for bottle fed ones though!
I had no probs following it with bf DS1, although sometimes it took him a bit longer to "progress" onto the next 'step' as ff babies (as I understand it) tend to be fuller longer than bf ones.
Sorry everyone else for this digression!
