To those with picky toddlers - do you offer a different type of food if they deny one? Or revisit same food?

I’m emotionally and physically exhausted. I’m pregnant aching and dealing with what I would describe the pickiest toddler ever to have existed. He will only eat a specific brand of grilled chicken strawberries and bread. And some other things but those don’t count as ‘meals’.

Please please tell me - those that have or have had picky toddlers. If they reject your dinner do you offer alternatives? Or revisit their meal later on when they’re more hungry? It BREAKS MY HEART to know he’s hungry but picky and won’t eat but he’s hungry. Tell me what to do please because I’m one second away from losing my shit and picking up dinner from the flood.
