Confused with BLW

my son is almost 6 months and I know my pediatrician is going to bring up solids at our next appointment but I have some concerns and thought I’d ask here for advice prior to that.

My two main worries are that my son could choke or not get enough iron. I’m also worried about how to incorporate solids into our current schedule since my son is EBF. I want him to gain weight and I know that breastmilk is probably the most nutritious thing for him right now. I just want him to get enough calories and nutrients and I guess BLW just seems a bit more complex than “baby eats what mom eats” the more I look into it.
