I think you've almost answered your own question!

Baby will fall into a pattern and it will generally start to fit in better with your lifestyle over time. The first bfs that got dropped in our household (by DD) were the overnight bfs. I encouraged this by making these ones very sleepy, quiet, dark, etc. And naps generally start to follow a consistent pattern as they grow. When they're little, I think you tend to follow baby's pattern (which it is) and then as they get bigger, they fall more into what everyone else in the family does.

But there is nothing wrong with holding out for a bf when it is inconvenient for you as long as he is settled and not screaming for a bf. I also found when I wore DD in a sling she would go for longer between bfs as well, so I'd do that in the mornings where I wanted to have a lazy leisurely shop and not have to stop numerous times to bf!
