baby not opening his mouth for food

My son is 6 months and started solids 2 weeks ago. He WILL NOT open his mouth to get the spoon in. I’m able to get it a little bit near his tongue in hopes in goes to the back of his throat but more times than not, it’s a fail. He sees his bottle on the table and always gets a bottle after some baby food and just puts his arms out for his bottle. Help a mama out! Would led weaning be more beneficial?? (I think that’s what it’s called) He LOVES grabbing anything and putting it in his mouth.
