I'm with shani - if your bub is handling lumps well, then give some simple finger food a go. Your bub may only play with it to start with, but will soon work out how fun it is to eat it.
I think some easy introduction foods is a piece of what ever you feed bubs already - say some cooked pear or pumpkin. It will be messy, but a good one to use as an experiment. You can watch what you baby does with it, how they learn about the texture by squishing in their fingers etc. Your baby will gag a bit, that is really common - a good reflex so don't panic. Offer a bit of water after (good time to introduce a sippy cup).
The type of bread isn't a big issue, brown, wholemeal, white - what ever you eat will do. Toast is a nice one to start with, crusts off - cut into 3. They tend to suck on it so it goes soggy. It can feel a bit hard in their little mouths and some times they can bite bits off, so maybe try that after some softer finger food - just so you feel more confident in your babies abilities.
Other good ones is some meat to suck on like a bit of chook breast or ham (if you happen to be eating it).
Best of luck - it is such a fun time.
