We have always done a bit of both with DD. We had to because she was always so small. She now pretty much does everything herself except foods like yoghurt. I guess it's personal choice. Some bls say not to put anything into the Childs mouth, it comes down to what you're happy with. If you don't think she is getting enough & she seems hungry then if you're happy to feed her afterwards then why not. That way she is still getting the benefits of bls, exploring foods, making choices etc. Maybe give her smaller portions if you're worried about wasting food.
