Is anyone's baby eating weetabix yet?

Ra

My boy will be 7 months on the 23rd. He's going well with completely blended purees and eats more or less everything. He's now having 3 small meals a day on top of his milk. He normally has baby porridge for breakfast but I can't seem to move on from this. He won't eat normal porridge oats he gags and is sick. I've even tried blending the oats before make it. Today I tried weetabix and he struggled so I stopped I didn't want to put him off. Should he be able to eat weetabix yet? I'm a bit scared to give finger foods yet. He has had a few of the baby puffs that melt and he managed them.
