My DP's eldest DD is nearly 16. She's quite clear about what 16 year olds do. In her view they are adults who can:
- Stay out all night wherever they like
- Stay home alone if the rest of their family wants to go of on holiday
- Get any part of their body pierced
- Go off on holiday/to a festival with friends
Her mum doesn't agree with any of this and alternates between screaming rows with her and throwing her hands up in dismay and emailing DP telling him to "make her do XXX". DP tries to reason with her but she's a strong-minded girl and he's is a bit clueless really - he went to boarding school himself and doesn't really know where to start with boundaries, and DSD is quick to exploit this. She lives with us at weekends, and her mum during the week btw - though tends to choose for herself which house to be at some of the time, which is fine if she's choosing a house that there's someone in at, less so when she's choosing to avoid the rest of the family and host parties at the house of whoever's gone away....
But 16 is kind of an adult isn't it? What sort of boundaries do you keep in place at that age? And how do you enforce them? She's staying on a school doing A-levels, but has a Saturday job so financial sanctions don't hit her that hard.
