When DD was born the advice was start with purees and introduce finger foods pretty soon after to help their coordination, introduce textures etc. This is what I did, but the first few months were pretty much just purees as finger foods would drive her mad with frustration - she just loved food and hated that it wasn't all ending up in her mouth. Purees also gave me more control over what she ate as there are food allergies in the family that I needed to watch for. She was always BFed (then bottle when I switched) before her 'meals' until she was 1, or they would be a snack between milk feeds.
Lucky for her she has good fine motor skills and coordination so, same as Elijah's mum said, could eat full heads of brocolli by about 8 months and was almost exclusively self feeding (spoon or finger food) by the time she was about one. This is the messy bit, BLW or not - learning to self feed. I know parents who still don't let their 2yos self feed, and think this is why some parents judge the whole 'spoon feeding' thing (as I'm judgemental of leaving it that late too).
I find the name BLW a bit confusing - as in it suggests what I did was not following my DDs lead. But if you'd seen her lunging towards her spoon of mush (compared to screaming in frustration that she'd dropped her piece of pear for the 15th time) you'd say I definitely followed her lead.
For the record, she's about to turn 5 and is an amazing eater. I'll do the same again with next bub, follow their lead ... wherever they lead me!
