Friend of a friend was unimpressed that 3 days a week my 3 year old son eats porridge for dinner. She's very into her home cooking. I cook from scratch too but I'm really not passionate about it. I cook basic meals like chilli, risotto, bolognese, homemade soup, lasagne. Roast dinners I buy a cooked roast chicken and roast my own veg, do my own potatoes. I'm just not passionate about it, and I'm happy as long as the food is healthy, whereas she's really goes to town with the cooking.
My son does 3 days a week in nursery and when he gets home at 4 he's tired and a bowl of porridge hits the spot nicely. He bloody loves porridge and often has it for breakfast too. I cook it with an egg yolk and chia seeds in and he usually has it either with sliced banana on top or applesauce and a sprinkle of cinnamon.
I think that's a lovely hot meal after a day of playing outside in the cold at nursery. It's healthy so I don't see the problem, especially as he has a hot meal at nursery every day. Today was fish pie. They have a different hot meal and pudding every day as well as two healthy snacks provided. Friend of friend reckons it's not good enough and he should have a "proper" dinner. Honestly, I often have porridge for dinner myself too!
