Purees with other food to play with is a great idea.
BLW is a good concept, however it isn't suitable for all bubs so best to just try and see what suits your DS. It would never work for our DS as his fine motor control is really delayed, and he would never end up eating anything.
Like Tiggy said, a combo approach is great. You sound like you're doing a great job. It is daunting though at times, especially as it's a whole new world to a new mum.
