So glad you are getting good nights - it makes you feel a bit more human doesn't it?
You are right that Tracy did say to start as you mean to go on, BUT what many of us have found is that trying to have all naps happen in the crib at such a tiny age is incredibly hard work and you can feel like you are spending all your time trying to get LO to sleep. The advice about naps wherever is very much survival advice - for myself I feel that the well-being of parents is every bit as important as the well-being of LO, and that the early days should be for enjoying your time and cuddles, not stressing about developing the perfect routine or habits.
As I said above, DD had very few naps in the crib until nearer 3/4 months of age. She was also fed to sleep a lot in the early days, partiularly at BT and I continued to feed until very drowsy at BT for quite sometime. Gradually she woke up more after feeds and we adapted to avoid feed to sleep. But it took time. I absolutely believe (and think Tracy would have said too) that you need to do what works for your family, and that means teaching independent sleep if and when you feel ready. I now have a fiercely independent sleeper - can't help her go to sleep if I try!!
At this age I never woke DD but again it has to be what you are comfortable with. A gentle way to try to establish WU time could be to allow a WU 'window' of say 30 mins either side of your ideal time, treating anything before that as a NW and waking LO if they reach the later limit.
Hope that helps, please just ask if we can help more
