DD1 has somewhere picked up on the concept of children's homes, fostering and adoption and is thoroughly confused and (I think) worried that someone might take her away from us and "sell" (her word) her to someone else I think one of her little friends has been telling her scare stories.
Did my best to explain how sometimes a mummy and daddy might very sadly not be able to look after their child, so another kind mummy/daddy would look after them instead. But she just keeps saying "why?" Why wouldn't they be able to look after their child. What might happen etc etc.
How on earth do I explain and also set her mind at rest that there is zero chance (I hope) that anything like this will ever happen to her? She's six.
