i don't have a teenager but i think you've handled it really well - you stuck to your guns & put the responsibility back onto her. how did she take it when you said you weren't driving her to the station?

i don't think you're asking too much of the 3 older kids - you have work as well as home life to keep organised & you should be able to expect some help. you're also demonstrating that there are consequences for not helping & that's the really good thing - it shows that you mean it & it's not just words. did your DD1 have a reason why she hadn't done her part?

anyways, wishing you lots of luck & you're definitely not being nasty!
