Helppppp toddler becoming picky eater!

My son is 17mo and I know it’s probably a phase but I’m terrified of having a crazy picky eater on my hands. He used to eat everything we did (veggies, salmon, proteins, etc.) but now he refuses almost everything!

I continue offering everything as usual but it’s been like this for WEEKS. I obviously don’t want him to go hungry so if he refuses everything from dinner, I end up making him something I know he’ll eat. I’ve tried doing one new thing, one thing he likes, etc. but he does not branch out anymore.

Am I doing things right or wrong? Lol I know these phases happen but I just don’t want to set him up for failure.

(I already follow all the major IG accounts like feedinglittles but wanted other people’s experiences)
