Baby-led weaning can be defined as "letting your child feed themselves from the very start of weaning... You just hand them the food in a suitably-sized piece and if they like it they eat it and if they don’t they won’t.... No purees, no ice cube trays, no food processor, no potato masher, no baby rice, no weird fruit and veg combos... just you and your child, eating food that you enjoy with you and your family." 
This is something we did with Julia since 27 June (2015) when she was roughly six months of age, that is, when she can sit up and grab things and bring them to her mouth (reach for food alone). It was a great success! Julia eats well and tries everything.
Then, we repeated with Luz, starting 16/10/2020 with a peach piece (just sucking).
