Obviously I don't know what your mealtimes are like or how you are feeling, but here's a couple of thoughts...
...babies tend to pick up on adult anxiety pretty easily. If you seem anxious or over attentive, are fussing about her eating, she might be picking up on it and be responding to it by refusing to eat! Perhaps try ignoring her whilst she's eating, I mean, give her familiar foods at the table with you at mealtimes but don't make any comments or encourage her, if she picks it up great, if she licks it great, if she bites it great, if she chews it great, if she swallows it great but don't worry if she doesn't - just calmly say "you obviously weren't hungry today darling" and clear the food away. Do the same again next meal - honestly, she'll eat when she's hungry - babies have a survival instinct!
...also, do you ever have other kids over to eat? Eryn loves to watch her big sister and is now trying to mimic her. Other kids can be a great motivator - the right sort of peer-pressure really! If your dd sees other kids eating, she might just want to join in with what they're doing?
...or have a picnic! Freya has always eaten better when it's a bit fun - sitting at the table with mum and dad = dull! Sitting on the carpet on a blanket and eating out of tupperware bowls with her picnic basket set for plates etc = fun!
I'm no expert in nutrition or anything, but if she's healthy and gaining weight steadily, I wouldn't panic. Just make food fun rather than stressful and I'm sure she'll get the hang of it!
HTH?
