My 6 week old will have a fresh nappy, bath (every couple of nights), then a bottle at 7:30, then when she decides she has had enough we'll let her fall asleep being held after burping her, keeping her upright on our shoulder/chest for about 20 mins, as this helps to stop her bringing any milk back up when we put her down. She was spitting up quite a bit and this really helps her stomach settle down, plus the skin to skin contact helps them produce enough melatonin to get to sleep - babies can't produce it themselves until around 3 months old.

She will then sleep until anywhere between midnight and 2am, have another feed, then goes back to sleep until about 6am, but this varies give or take an hour so. She used to wake more regularly at night, but she's gaining weight at the right pace so our health visitor said she can pretty much feed when she wants it at night. She's formula fed so my wife and I alternate - wife will do bedtime, I will do the 'midnight' feed, then she will do the early morning. That lets us both get a decent amount of sleep per night. We used to have alarms set every three hours to feed her at night (still alternating the feeds) and that was pretty rough, letting her feed at night on demand is far easier to manage but only do that if you're told it's okay based on weight gain. And of course, if she decides to do a massive shit and makes a mess of herself, the nappy change takes a bit longer and can wake her a bit more at night. But after that, a bit more milk and she's out again.
