My nine-year-old niece told me that every morning she makes her own - and her 15-yr-old sister's packed lunches every morning before school.
She also regularly turns up for sleepovers (at ours and her father's house) without a hairbrush, warm jumper or enough clean clothes because she packs her own overnight bag.
On one occasion on a weekend away, the 9-yr-old slept in her clothes and hardly washed - her mother either didn't notice or didn't care.
When asked about this, their mother says that they are encouraged to be independent and do things for themselves.
She thinks IABU to think the nine-year-old has too much responsibility for her age.
Go on, Mumsnet - give it to me straight!
