by the time your child is 1 year old, he/she should be eating everything that you are, but in smaller pieces and smaller quantities...as such, at 11 months, you should be getting pretty close to giving your little one MANY different things.
i have met so many people in hk that only feed their children congee up to 1 year, that they have a VERY hard time getting their kids to eat anything else.
personally, i can't stand congee (both of my kids LOVE it, though) and i can't understand why people here are so stuck on giving it to their kids? it is bland, boring, with not much texture or flavour. that is a sure-fire recipe for a picky eater, i think (could be wrong).
i think experimenting with food is fantastic. it opens so many doors to so many cultures/tastes/flavours. i thought it was awesome that my 2.5 year old LOVED salmon sashimi WITH wasabi!
don't be afraid to experiment, it's not like your child is going to eat the same things every day for the rest of his/her life. a little bit of salt won't kill them (a lot could damage them). so long as 90% of the food your child eats is not salty, then he/she should be ok.
of course, all of the above is only my opinion, and i'm sure there are many out there who will disagree.
