When my foster sister first came to live with us I found it hard. It felt strange having another person calling my parents mum and dad, and I was jealous of the attention she was getting.
I also felt really guilty for feeling like that so it was a real mix of emotions.
With Fixers I've made a booklet that is aimed at the children of families who are planning to foster.
It explains what a massive change it is having another child living with you and that it can feel difficult at the beginning.
I think some families are put off fostering because they are worried about the impact a foster child will have on their family, but they shouldn't be.
People need to know it can be hard, but also that it is worth it in the end. Now my sister and me are the best of friends.
Comic Relief and Kim Cormack and Sarah Jenkins from Five Rivers supported me with this Fix.
