My DS (9) recently had a birthday so had some money in his room. Partner's child (11) and DS were playing in my DS' room and partner's child asked my DS for £10 - my DS said 'no'. Partner's child then said give me that £20 or else I won't play with you. My DS then left the room leaving partner's child in his room. When he returned the £10 had gone.
This has come to light as my DS was with his nan and she was talking about asking to borrow £10 from me and my DS said she could have had his £10 but 'partner's DS' took it.
How would you handle it with the partner and his child? I believe it happened as my DS doesn't lie and also the way it came to light. Plus partner's DS has previously taken money and lied.
My partner always says to treat his children as I would my own. I'll be going there later in the week, should I have a quiet word with his DS and ask for the money back - however, I think he will deny it. Should I speak to my partner first before I say anything? Should I handle it or let my partner deal with it?
