Looking at other peoples suggestions, and your replies and most importantly, the fact that she eats well at nursery I would say that it is your OHs (and maybe your) eating habits that are influencing how she eats at home. As I said in my previous post, me and DH love food and cook from scratch everyday. We had a high chair for DS that was suitable for newborns and so he sat with us at every meal. It was incredible how much he would watch us! If you are really on board with cooking and eating home cooked food and your OH is not, perhaps it would be beneficial for the time being for him to eat at a different time so that DD can observe your positive eating habits.
As others have said, perhaps she is just a snacky eater and so maybe she would do better with meals like fajitas? What is the meal schedule at nursery? How many meals does she have there? Perhaps she is just not that hungry if she eats loads at nursery?
@Greys007 has given some lovely meal suggestions. I’ll add a few of DS’ favourites too.
Breakfast: toast with butter/avocado/ peanut butter/ cashew butter/ almond butter, crumpets, cheerios and full fat milk, porridge (with banana, berries etc), full English with a bit of sausage, scrambled egg, mushrooms, low salt beans etc. What mummy makes has a delicious recipe for pina colada porridge made with coconut milk and pineapple.
Eggy bread with various fillings. He loves eggy bread topped with cheese and finished in the grill.
Lunch: sandwiches, breadsticks, hummus, rice cakes, pinwheels with assorted fillings, soups, jacket potatoes with cheese and beans, quesadilla with cheese, sweetcorn and tuna/cheese and chicken/ avocado and tuna, omelette with various fillings, leftovers from the night before
Dinner: roast dinners, homemade burgers, homemade pizza, turkey gnocchi, fajitas, various curries (lamb or chicken), slow roasted brisket, homemade chicken kebabs and flatbread, homemade oven baked chips, sweet potato wedges, salmon (with a mild chilli topping) with rice, chicken stroganoff with rice, tarragon cream chicken with rice, cheesy pasta, pasta and beef ragu, meatloaf
All served with a variety of veg but he especially loves broccoli and green beans.
