My girl is 1, and I still give her puree and solid food. I let her feed herself and when she goes to open up her mouth I put my spoon in.
It's very frustrating and I do understand you.
I hope you find answers soon.
Is there anything you have not tried?
Mash potato with sour cream or cheese?
I've actually been looking to make new things, but hardtop find the time. But I'm getting there.
