I don't know if IABU but our au pair eats a lot. To the point that I have changed supermarkets to be able to keep costs down and it takes food away from the DCs.
For example, yesterday she had 3 southern fried chicken breast, half a packet of fresh spaghetti and 2 chocolate bars for supper.
She'll have scrambled eggs and toast for breakfast, pizza at lunch and then a large supper.
I have started to write a menu for what the DCs are having for supper so she doesn't eat it.
However, this doesn't make much of a difference.
Our previous au pairs never eat this much and I am finding it hard to keep up.
