Hi OP — following with interest as we had some similar experiences in my childhood home.
Responses to this are probably going to fall into a few different camps, because approaches to issues like this are often rooted in people’s core parenting beliefs. Some people lean towards stricter consequences, while others focus more on understanding the “why” behind the behaviour and helping children develop self-regulation over time.
As the older sibling of someone who later developed an eating disorder, I’d just encourage a bit of caution around how food-related consequences are handled, especially at this age. One thing I think about a lot as a parent now is: when my children are adults, how would I want them to describe their relationship with food, boundaries, and discipline growing up?
In our family, consequences around food sometimes seemed effective in the short term, but over time they also created a lot of tension and shame around eating. My sister and I (who were around the same ages as your daughter when these struggles first began) have both done work as adults to unpack some of those patterns and build healthier relationships with food.
My sister and I were actually messaging about this thread earlier and reflecting on how differently we approach food with our own children now. For us, food isn’t a reward or a punishment. We try (not always successfully — Easter chocolate definitely humbled us!) to give our children opportunities to practise moderation, while trying to remember especially in the moment that self-regulation is a skill that develops gradually and imperfectly.
When things don’t go well, we try not to shame or overreact to the kids, but instead see it as part of the longer process of teaching and modelling healthy habits around food. We’ve also found that if we relax one boundary eg eating away from the table we usually need a bit more structure elsewhere, like portioning things out in advance, checking everyone’s got what they need before eating, or if we are eating whilst watching something we need to remind then to eat until they feel full not just keep eating because they are distracted
not a perfect science or a perfect approach but wanted to share
