Moms who have done baby led weaning??

I have some questions about baby led weaning. I would like to start my daughter at 6 months but I'm concerned a out iron intake. I have read food before one is just for fun however we know babies need more iron around the 6 month mark. I am a vegetarian but baby will not be so I need some ideas for meats that are suitable for baby led weaning. Also I'm assuming much of this will end up on the floor. So if baby isn't actually eating then how can I be sure she is getting enough iron? Thats really my biggest question!! But I would love to hear others experiences with the whole approach!!
