My dd was closer to 8mths before she really ate anything that I would call close to a meal. Her problem was trying to drink the food off the spoon, so I found if I made it really liquidy in texture she slurped it off for a few weeks and then gradually got the hang of eating it off the spoon. She also very quickly went onto finger foods and completely skipped the lumpy mash stage.
DS didn't like rice cereal at all, so I only did fruit and vege combo's with him.
I found with DS in particular, he took about 10 'tastings' before accepting a new flavour. I would just offer it every day, but not make a big deal of it and one day he thought it was ok. What you can also do, if she likes pumpkin, use that as your base and add new things to it even while doing your "allergy" testing and then reduce the amount of pumpkin gradually and you have a new food to then use as your base for trying a new food. Pear was used as our base for most foods (even what sounded like disgusting combo's went down well).
