Amani, I wouldn't worry too much, IME they tend to stretch the time out all by themselves. DD fed every 40 mins to begin with but by 8 weeks was every 3-4 hours-I didn't dothing to change it, she just started going longer. The last couple of days ds seems to be going longer too but I know a growth spurt will soon change all of that!
On the same note, Wizz, I think the books are great as a starting point but don't stress yourself trying to follow them to the letter-at the end of the day you have to do what suits you and your baby. Rory is still very little and I don't think you are doing any harm by letting him sleep on you if thats what he needs for now-he isn't going to forever! Obviously when he gets a bit older you can try to enforce good sleep habits a bit more rigorously but for now it won't spoil him.
So just being nosey, who is following a routine already, who intends to, and who is very firmly in the laissez faire camp?
We seem to have accidentally fallen into a kind of routine-still very much feeding on demand, rocking (well more walking and bouncing!) to sleep but ds will usually go back to sleep after his first morning (ie after 7am-anything earlier is NOT morning in my house!) feed so I then get up, get dd up etc. Feed whenever he wants it during the day (mostly every 3 hours at the moment but 2 days ago was every 1-2!) then he tends to wake at around 6 every evening so I then bath him, sleepsuit on and feed him. He is then usually asleep by 8 so into his crib. DD goes to bed between 7.30-8 so in theory we have the evenings to ourselves-woo hoo! Except I'm so knackered that I'm going to bed by 9 myself! DS will then wake between 10-11 so I'll feed him, change him etc then pass him to dh to settle him to sleep, then whenever he wakes in the night (usually between 1 and 3) I'll do the same but have to settle him myself. That's the killer cos it often takes him 2-3 hours to settle at this time which is why I feel absolutely no guilt at dh having to do the earlier one! He sometimes also wakes at 12 and usually at 6ish but takes less time to settle then and doesn't always wake. That's about as much routine as I can handle really, I find them really hard to follow! It's all what works for you though isn't it, a friend of mine is always horrified at my ish attitude to timings-her dd has fixed times for all meals, naps etc and she follows the routine religiously and both she and her dd are happy and relaxed doing so.
Macdoodle sorry to hear of your concerns, hope all is ok
