Can fruit purees combine with early fingerfood when starting Baby Led Weaning with an almost 6 month old?

Hello from barcelona ! I read all your articles and you are the only one sayin-(in an article)-that purees can be combine with BLW. I have a 5 month and we have heard pediatrist who told me to start with fruit purees. So I did. And then I discovered BLW...wish I haven't started the mashed Spon fed . Also my little, still to little to hold his back straight. They say when they do purees first learn to swallow without chew & use hands
