Hi, couldn't reply all day today, i was working!
Baby whisperer is a great book - it really helped me communicate better with DS when he was born and gave me lots of confidence (in learning to recognise the type of cry, a tired cry, a hungry cry, etc.) I don't often recommend books because they won't fit everyone's taste, but it really helped me more with understanding the baby's needs than to establish a 'routine'.
The best way to recognise a pattern is to write it down, so for a few days, you write down at what time your baby eats and sleeps. You might be surprised and recognise some parters, then you reinforce them by sticking to the same time every day.
Also, some babies just need to suck - my DS never took a dummy he always spat it out (projectile!) but you might find that it will just reassure your baby to be held for a few minutes with the dummy, then take the dummy out and then go with some play time or a walk. It might help the next feed to be longer and more satisfying for him.
Another thing - 'schedules' get disturbed loads by teething which might be what's happening now. DS had his first tooth at 5 months and although he didn't cry much, he kept on waking up and demanding much more attention during the day.
as for the bottle, DS started taking a beaker before he actually accepted a bottle, so you might want to try that!
