Any premature moms here?

My son is 7m now but his adjusted age is 5m. I’ll be offering solids to baby in November. Do you begin with TW and slowly transition to BLW? Or straight into BLW? Do you follow 3 days wait rule? How should I start? A single food once a day? Or I can do breakfast lunch and dinner? Do I need to nurse baby and wait 30mins before offering him food?
