Yes,they are in our house.
5DC 6 DD,11 DD,12 DS,16 DS,18 DS.
The uniform is a lot more expensive in general when they start at secondary school.
All of our 4 older DC are in adult clothes and shoes although 6 year old DD has just gone into lady's shoes size 4 as well(I would go and have giants)so I should only really have 2 teenagers costing me a fortune but when it comes to clothes and shoes nearly all 5 DC are in adult sizes all ready.
The clothes,shoes and trainers cost us more for the older two as they're into brand names now.The 4 oldest cost us a small fortune in body sprays,deodorant's,perfume,aftershave,hair products anything to do with pampering and preening themselves really.
The oldest 4 are all into gadgets so that adds a fare wack to the budget each year along with mobile phone's and credit for they're phone's.
And the oldest two have hollow legs,they could eat for England.16 year old is a Rugby player and has a broader chest than most men and is nearly 6ft and oldest(18 year old)works now and has a very physical job,does weight lifting and is over 6ft tall so they both need to eat a lot to sustain they're size.
The good thing though is the older two would rather earn money than take money of Mum and Dad(which were both really proud of them for)and were both big softy's so they know they'd only have to ask for money but they don't.Oldest is in full time work and pays keep now and second oldest is in full time school but does dog walking every day as well to earn some money.
