SRV - I had the EXACT same patterm with my DS at around 6 weeks of age. He would be unsettled between 6-10pm, then go to bed quite well after this time. My suggestion is to continue to perservere with settleing him at 7ish, like you have tried, but stay in his room throughout the time that he usually needs resettling (so probably 20 mins for you) and quickly resettle as soon as he starts to grizzle without picking him up if you can, then stay in room for up to 10 mins more in case he needs resettling again (or wait just outside his room/close by). It takes forever to do it this way but I have found that over time it is really successful. It now takes me 15 mins in total to put DS to bed at 6.30pm and I don't hear from him again until I wake him for a rollover feed. Mind you, it has taken the last 6 weeks of doing this consistently every night for us to get to this satge. Oh, I also only settle DS in his bed awake (only picking him up briefly if he cries - I settle without picking up if he "whinges") - very hard work but so worth it as he now sleeps really well at night.
