Purees to "real food"

My baby will be 9 months on the 13th she just recently started pushing her spoon away and refusing to open her mouth when I try to feed her her baby food but if I put stuff on her tray for her to pick up and feed herself she does great with it. So my question is when did you stop pureed baby food and go to strictly finger food and what are some meals you give and how do you know how much to give? Thank you for any responses and I cannot believe how fast this year has flown by
