I have 3 teen ds 15,17 and 19.
They cook all the time. Breakfast lunch , I make dinner they then cook in evenings and when getting home. My electric bill is too high.
I’ve asked them to have cereal or toast or instant porridge etc for breakfast. Sandwiches etc for lunch and snacks to be something that doesn’t need cooking. We always have these type of things available but they ignore me and start cooking. I can’t remove the oven etc and they often do this when I’m out or in bed. Only 19 year old works so I can charge him more rent to cover his share but others still in education and I don’t know what to do .
