Some young people and adults will always find it difficult, or impossible, to make decisions for themselves. Every day, the people around them who care for them and support them, make routine decisions on their behalf based on their best interests.
As parents, you know what sorts of decisions your young person can and can’t make for themselves and act accordingly. For example, them choosing what to have for dinner may be fine – but not whether to take their medication (because they don’t understand the risks of not taking it).
You will be exercising your judgement on these sorts of issues day in day out, and be so used to doing it that you probably won’t even give it a second thought!
When they turn 16 yrs, these day to day situations won’t change – but the practitioners working with your young person will act differently when a decision needs to be made. Instead of asking you for consent, they will need to establish whether your young person has the mental capacity to make the decision for themselves (through a mental capacity assessment). If your young person doesn’t have capacity, then the practitioner will make a ‘best interests’ decision on their behalf. This might be so they can provide some new treatment or medication.
It can seem strange, or even be upsetting, to find that you can’t make the decision on your young person’s behalf any more but it’s important to remember that this isn’t because your views don’t count, it just reflects the change in the law.
