Ours is £120 including cleaning stuff. Nappies and wipes.
Usually DD has a free school dinner. So we are giving DD an extra meal a day. Eating more snacks here too. Probably boredom but they eat plenty of fruit.
If you shop every 7 days. Think of 7 meals you will cook for tea. .
Example.
Sausage, mash and veg
Tuna pasta
Stir fry
Chicken burgers and chips
Spaghetti Bolognese
Pizza and chips
Jacket potatoes and salad
Sunday roast
Then think of lunch. Do you have soup, sandwiches?
Then you need sandwich fillings
Soup.
Beans
Bread
Crumpets/ wraps etc depending on your taste.
Snack wise.
We buy 4 different fruits each week
Yoghurts
Cheese strings
Chocolate and crisps
Orange juice, milk and sometimes coke and squash.
Toilet rolls and cleaning stuff (max of £12)
Toiletries are only once a month when we need toothpaste, shampoo, shower gel and bubble bath. Soap too.
Never go over £120
Also I buy extra freezer bits like frozen veg, chips, veggie burgers and fish fingers.
