We had the same and had to resort to dancing fruit whilst she had a cold. I thought we were never going get away from it but now breakfast and lunch are absolutely fine and just use it for a bit at dinner if she is tired. I just started each meal without it and tried to distract with fave food/singing until the whinging got too much then I'd turn it on. After about a week she stopped needing it at all. I think it just took time for her appetite to fully come back.
Thanks both, the suggestions make me feel much better. We managed breakfast and a bit of lunch without it today so it’s a start!
You could try weaning like you would a dummy etc? Just less time each day during the mealtime until it’s no longer needed? I’ve not experienced this so just an idea!
