My baby (born 9/10) has been eating cereals and such for about 6 weeks now, and to be honest, this is my second child, my first was NOT an "eater". Don't force, don't bribe, don't trick. It's not worth it. If she isn't interested enough in eating to open up, she's either not hungry, not interested, or doesn't want to eat solids yet. I wait till mine is good and hungry to offer food, generally at lunchtime only. I forced my oldest to eat at this age and paid the toll for it later when she refused to eat at 12 months. Give the munchkin a biter biscuit or zweback cookie and watch her closely...let her get the hang of opening on her own.
Also, it helps if you eat with them alot. Hold her, and show her you eating. Eat slowly, taking care to show how you open your mouth to insert the utensil. She'll catch the drift more quickly with you showing her the ropes. Don't make it some big thing, just sit or stand with her in your arms or on your hip and munch on something. Even better, make it somethin you can share with her like applesauce. Take a bite, then offer her some. Prepare to get a little messy, but enjoy it!
Good luck!
