I feel I should wait but also I think he's ready for eating.
Personally, I would skip the rice cereal, it is really just calories and no nutrition (other than hard-to-digest iron they add in). Avocado was DD's first food. I didn't start solids until almost 10 mos when DD was capable of self-feeding so never did any baby food at all. Worked great for us. Just breastfeeding is waaaaaay easier than dealing with baby food, so I wouldn't rush. Also, breastmilk is so chock full of nutrition.
You may get more answers in LWAB though, I recall there was a lot of talk about this sort of thing when I had a little baby.
I'm thinking that Mother Nature is smart, and when we can feed ourselves, we're meant to start solids. I do understand that desire to spoon feed the "first foods" (especially with your first! trust me, it goes away after subsequent children )
If *you're* really jonesing to do that, freeze some breastmilk into a slushy/soft ice cream form, and then spoon that. That helps with teething and is great if you have a baby that won't take a bottle and you need a bit more time away between feedings.
Also, with my first, I liked this chart I think some of his food recommendations are a bit dated, but it's a good reminder of developmental feeding stages, IMO.
Mama to DS (8) and DD (7) Aristotle was not Belgian. The central message of Buddhism is not "Every man for himself." And the London Underground is not a political movement.
