Ashleigh doesn't like anything too chunky. I still puree her meat but vegies I just mash up really well so they're thick but don't really require chewing.
I do practice her once a day on chunkier type finger foods just to try to get her used to chewing but she isn't really impressed at all and will chew a little then spit it out.
I just presume (and hope) that eventually in her own time she will get used to it.
How thick are the purees? Maybe try mashing really well so the food is thick but without much lumps.
