I like to mix cereals sometimes. Kix with cheerios, fruity cheerios, etc. My daughter is 21 months and also likes the golden graham type cereal... different shapes. However, I like the shredded wheat, and I think the kids like it more than me. When I give it to my daughter I make sure it's bite size and has absorbed some milk, but she is a very good chewer and wasn't a gagger/choker.
Maybe you could also try hot cereal, or give her granola or wheat germ on her fruit, fruit w/yogurt, fruit cheerios and milk, flat bread or get out your rolling pin and flatten some of your own bread, spread pb & j and roll it up. You might try trader joe's for a healthy kid cereal.
If she is willing to eat things without much hesitation, maybe try giving her some new variety. My son stayed on babyish food until he was between 12 and 15 months. My daughter started wanting and eating our food around 7-8 months. She's petite, and doesn't eat a lot, but she likes fruit and vegetables and will choose them over junk. My son is the opposite.
She may even just be having a food jag and be liking a certain thing for a while. I swear my son will eat chicken nuggets forever....
Sorry for the long novel...
Good luck.
