How do i get my 16 month old to stop eating baby jar food and eat chunkier food?

i have tried to give her foods that my husband and i eat such as banana pudding(she eats a little bit), bread,cereal,finger foods like gerber graduates, fries, eggs, etc. but she won't eat them she just plays with the food then throws it on the floor. she will hold her sippy cup herself and takes her bib off by herself but she won't eat anything but gerber 2nd foods. any suggestions? i keep trying but she refuses to eat anything else. my mother in law don't help either cause she keeps comparing my baby girl to her friends granddaughter that's 4 months younger and already eating hamburgers and almost anything else off the table. any ideas on what to do?
