Thanks for your comments guys.... I have done a childsafe first aid course so I kind of know what to do for choking. I just worry that every meal is going to end up with me grabbing her out of the chair and smacking her on the back!
I think I'm going to go with the bit-of-both approach I have been using so far, bit of BLS and some fork-mashed stuff. fortunately she is a bit of a pro with a spoon and can grab it and feed herself so I don't feel like I'm shoveling. I guess it's just a matter of being a little anxious until she has it worked out.
