Hi there - I agree with what Poppy-Pop said.
I think the ABSOLUTELY worst thing that you could possibly do is to 'force-feed' her - just think about how you would like it if a much larger, stronger person than yourself would 'force' you to eat something you didn't like. And i really don't think that will make her eat the food - it will just make her anxious about mealtimes and scared of you even possibly?
Try looking at her food intake over a whole week instead of a day - some days will always be poor, the next she will/might make up for it. She seems to be eating a little of most food groups, so be ahppy about that. She will become more adventurous as she grows older. Continue to offer new foods alongside foods that she currently eats. If she doesn't eat them, no big deal, IT IS NOT THE END OF THE WORLD - try and remember that.
I know it's hard - I have a VERY fussy 2.5 year old. I just go with the flow and try and make sure she doesn't have too much junk food, sugar or salt in the foods that she DOES like to eat, and not let her have cereal for every meal every day, whcih she would have most days if she could! :roll:
Let us know how you get on
