My 9 MO sounds just like yours. She loves mush from the spoon, she will also take mouthfuls of things which I break off and pop into her mouth (bread, potato salad, sarnies, soft fruit etc etc), but she finds it hard to pick things up and put them in her mouth. If she does pick it up, she tends to look at it intently, give it a squeeze, then drop it disdainfully.
I noticed today that if I left her alone, she was more likely to try and put stuff in her mouth herself - it seems that if I'm sitting with her, she expects me to feed her. But without me there, she'll have a go herself. So I pottered around, putting washing away, pretending not to watch her, and she munched on a sandwich with interest. I think I've made it worse, as I've always just fed her as I've not got the patience to watch her try!
I like the fact that she eats mush, as it means I know what she's had, and her weight gain is good so I'm consoling myself with the thought that she'll get there in the end, and in the meantime she's still eating well. So if you are failing, then so am I, but I think it'll work out OK! :)
