Personally I wouldn't advocate putting the food in her mouth, it could be dangerous and I also think you're losing the whole idea of bls that way.

What time are you feeding her dinner? For a long time, if I gave DD dinner after 5.30 she wouldn't touch a mouthful, and by moving her dinner slightly earlier she would happily eat. I've also found that DD is a grazer - she much prefers to eat pretty much all day, and I'll happily give her a snack an hour before dinner, or something to nibble on while I'm cooking, which is always the worst time of day for her being cranky. Now she eats loads throughout the day, and I don't stress if dinner's not doing it for her that night. I do usually have an avocado and a couple of cruskits on stand-by at dinner time just in case she's not into what we're eating though!

ETA - I reckon it's just a learning curve too, I'm sure in a couple of months she will have learnt so much more about eating and you will wonder what you were stressing about. I am still regularly astounded by DD's progress at 14 months.
