When Bethanie was 1, she ate our food.. but mashed down a fair bit. I think all babies are different and you will know what size chunks she can manage. Just go with the flow with chunk sizes, remember not to add salt/too many stock cubes or sauces to your cooking and see how she goes with it.
We did still give her jars for ages after she was eating with us, except we only used them on emergency quick dinner needed nights and if we went out and didn't have time to prepare a whole meal for her.
