With all three of mine, I basically went with the flow for the early months, and as time went by, things settled down into more of a routine. By the time they were 18 months old, they had a pretty good routine - a nap after lunch, and bedtime at around 7.30pm, and sleeping through most nights, until 5.30 - 6am.
8 weeks is really young to be trying to get I to much of a routine, but you can start with a bedtime routine of bath and feed early evening, with things quietening down in the house after that - in the hopes that the baby will sleep for a while, before a last feed of the night, and then whatever feeds he has in the night.
You could set a time in the morning by which you want to have got him changed out of his night time baby-gro and into a daytime outfit - I did that most days (though there is nothing wrong with a baby living in babygros) - I just liked having them in the nice outfits they had.
But don't beat yourself up if no routine emerges, or if you can't get into a routine yet - it really is early days, and going with the flow really won't mean a baby who never has a routine. I went with the flow with all three, and by the time they were toddlers, we had a fairly regular bedtime and daily routine - but I honestly think it was a good thing that it wasn't too rigid. We made the routine work for us, we never felt that it was in control of our lives - so if lunch was late, because we were out and about, the boys coped just fine with that. Same if we were coming home late from somewhere - they could nod off in the car. They needed a nap after lunch, but that could flex too.
One thing I found really helped with putting them down in the Moses basket was swaddling them - which another poster has mentioned. I figured that it was going from a nice warm cuddle with me or dh whilst being fed, into a chilly Moses basket that was waking them up when they were drifting off nicely at the end of their feed - so if they were wrapped up before the feed, the warm blanket around them provided insulation from the chilly mattress. If you didn't want to do that, you could put a warm hot-water-bottle I the basket, just to slightly warm it up before they go in - not hot, just warm enough not to wake them by being chilly, if you see what I mean.
Remember, parenting is a marathon not a sprint, and you have lots of time ahead with your beautiful baby to get into a routine - and you might find it easier and less stressful to put the routine aside for the moment.
If you take nothing else away from this essay post, take this. There is an amazing book by the Radio 4 journalist, Libby Purves, called "How Not To Be A Perfect Mother" - full of the things she and her friends learned at the coal face of motherhood - the practical,hints and tips for getting through the days.
As she says, we are told we need to be the perfect Madonna, the mother who does it all right from the word 'go' - but even a Madonna needs time off with a cup of tea and a good book! And it doesn't matter if, occasionally, the baby is in a disposable nappy, and his older brother's jumper with the sleeves rolled up - as long as he is warm, fed, clean and happy.
Basically we don't need to stress about every little falling away from perfection - we need to be good enough. That is what I lived by, and I have two strapping healthy sons at university, one graduating in Law this year, and the other reading Maths, and a third equally healthy and strapping lad in his final year of school, doing his university applications.
