stop for a week and then try again. At the beginning create a positive association with a high chair- give them a new toy and take them out after 5 minutes. Few days later put food on but don't encourage them to eat just leave them in front of them. And gradually move from there 😊
I agree with Klaudia. Just stop for a week and try again x
Have you tried giving her the food sat on your knee? And you also eating from the plate with her?xx
