I help out a friend of my partner's who works with him by picking her son up from school with my son as I'm a stay at home mum. She pays me to do this monday through Friday. Anyway, her son started to have money to spend on sweets on the way home every day, something I don't give me son as firstly, I can't afford it and secondly, I don't spoil him. At first he would share the money with my son but then he started to run off and spend all the money on himself and my son would have nothing as I don't carry cash with me anyway. At first I thought it was just silly kid stuff but then I noticed that he knew it was upsetting my son and would wind him up about it knowing he would get sweets and my lad wouldn't (we're talking £2 every day!). Eventually I had enough and I politely asked his mother if she wouldn't give him money every day as it wasn't fair for one to have sweets and not the other. I found this quite embarrassing (having to say I can't afford it) and awkward to do. He did one day (the day after) with no money then turned up the next day with money again, upsetting my son and rubbing it in his face. Now I'm totally stuck with what to do and how to bring it up again with the mother?? Help anyone???
