Well, after 5 tries of rice cereal, I thought I'd be adventurous and try green beans last night. It wasn't a hit. You would have thought I was feeding him brandy. (I would have given the same expression had I taken a sip of brandy.)
Notice how he looks like he is going to puke. Lauren is having a blast laughing at him.
After I went to get rice cereal to mix with the green beans, I gave him a bite. That was all it took. He threw all of it back up.
