Yes, mine have been self sufficient since long before year 6. Once they get to secondary they need to be able to organise themselves, so you're really doing her any favours running round after her at that age.
It started really because DS1 was always very argumentative in the mornings, moaned about everything I put in his lunchbox and generally made mornings a nightmare, so I just started staying out of the way. I would make a cup of tea and retreat to the sitting room or back up to my room while he got ready, then help the younger ones, who left half an hour later than him.
Once the younger ones started secondary and started getting up at 6.30 I realised that I wasn't adding much value getting up at all, as they were all ready to go by the time I even got downstairs, so now I stay in bed. I'm a night owl and don't start work until 10am most days, so I don't need to be up as early as them.
They get up, get showered, make themselves brekky and remember everything they need without any prompting from me (except the odd day they need to take a toothbrush for an orthodontist appointment, or cooking ingredients etc) They will usually pop into my room and say goodbye before they leave.
DD is the youngest of 3 and has always had to be self sufficient as getting 3 of them ready for school and nursery meant everyone had to be able to put their own shoes on and eat their breakfast without making a fuss.
