Feel like I'm starving my boy - okay not literally I'm aware there are real starving children in the world.
But my ds has a cooked school meal which he normally has 3rds of (both main and pudding), therefore I don't normally have to do packed lunch.
If we are going out for a picnic I always take enough food to feed anyone else who happens to be in the park that day. 
Anyway tomorrow my 6yo is off for a full day of sports and needs to take him a packed lunch - I have just packed:
a round of ham sandwiches
chunk of cheese
grapes
apple
2 fairy cakes
penguin
Apple juice
Water
DH says that is plenty - I've said he's going to be famished. Do I need to do more???
