11.5m old baby and weaning

FTM and I need some advice or reassurance on what happens once my baby turns a year.

Right now, my LO is drinking 27-30oz of formula (he loves his milk). I do offer him solids 3x and sometimes a snack. He loves his puree (will eat anything if pureed) but it’s a hit or miss with “real” food.

What do I do when he turns 1?!?! He will be off his infant formula and will transition to whole milk but from my understanding, he shouldn’t be relying on whole milk right? Im genuinely nervous….
