We were kind of the same at that stage. We started Isaacs bedtime routine at about 11 weeks, that's been a great success.
As for the daytimes, I wouldn't call it a routine as such but we follow a cycle of eat, activity/playtime, sleep and time for Mummy whilst he's napping! Usually to do the cleaning!
There aren't set times for his feeds, it all depends on when he woke up for a feed during the night. Sometimes, he wants more play time than other times, we just go with the flow of things. I guess our only routine is the pattern we follow as mentioned above. I don't like the idea of a routine marked out by times etc...that sounds very rigid to me.
Isaac is the same, he varies how much he feeds even now, he will go 3/4 hours between feeds for the most part unless we've been out somewhere in which case he may go longer.
Isaac is still waking up twice a night, it feels like he'll never go through the night - just our luck but then lots of people have told me that it just happens out of the blue. I'm still hoping
It sounds like you're doing really well, go with what you feel is right for you and your baby.
