Mine was the same. I think the commercial food had a very smooth, even texture that he found easier to start with. Once he got the hang of chewing, he preferred real food. He's 9 months now and has two teeth. He eats cubes of cheese, bits of egg, ham sandwich, pasta twirls, bread and hummous and bits of whatever we're having. I wouldn't worry about it. He'll be getting most of his nutrition from milk at the moment anyway.
