We see my DM every week and she always gives my DC age 2 and 4 a kinder egg. They love getting them and have come to expect them when they see her. They scoff the chocolate but really couldn't care less about the toy. I don't mind her giving them a treat when she sees them but it's the plastic tat I can't cope with. I have made comments about them not seeming fussed about the toy and they'd be just as happy with chocolate buttons and she replied that they're not special enough. Can I outright ask her to stop buying kinder eggs or is that ungrateful and mean?
