hi again... i had the same problem. no worries at 7 months with all the 1st pureed foods in jars, but would NOT eat anything out of a jar with texture. ie 2nd & 3rd stuff. i tried everything, cold straight out of the jar/can, heating it, giving it to him when he was hungriest first thing in the morning. no go. but noticed the same thing - he would eat off my plate.
have you smelled/tasted the stuff? it's disgusting. i don't blame him.
so, i started to cook for him. granted it takes time. but, most veges can be steamed in 10 mins, and cut in little pieces, they can pick them right off the tray.
fruits, i will still mix a jar with cereal, or give him fruits he can eat raw. ripe pear, grapes, strawberries, grated apple, peaches & pineapple (out of a can), kiwifruit.
pasta and rice he will eat. i overcook them a bit to soften more.
meat & fish, i cut into little pieces or buy ground beef, veal etc.
i still have some jars of food left over and i put them in the nappy bag to use if we are caught out. and to this day he will not eat it!
