Toddler obsessed with sugar

My 3 yo is obsessed with sugar and chocolate. We don't eat a lot of it as a family and I'm very careful about making sure we all eat a balanced and nutritious diet - 95% of what we eat is home prepared and unprocessed food. We make plenty of desserts and sweet snacks that have no sugar in them.When he started to get fixated with sweet things, on the advice of a family member we limited them to only being allowed at weekends. That turned out to be really hard to enforce properly because of playdates, grandma visits and holidays and worse than that, got to a point where every day he wakes up and asks "What day is it today? Is it the weekend?" He also wants to eat chocolate and sweets all weekend, and every meal time at weekends is a fight. So, we're binning that idea.The plan right now is to go cold turkey for the next 4 weeks with no sugar in the house and no sweets or chocolate at the weekends, as something of a reset. There will probably be some things we can't control (they do cakes at nursery for birthdays, for example), which is fine. We're undecided what to do after that, though. I don't want an all-out ban because I don't want sweets to be this desirable, unobtainable thing, although I'm really happy to not have sweets in the house in general.Has anyone successfully dealt with a sugar obsession before? Or just managed to develop really good food attitudes? Any and all advice welcome... via /r/Parenting http://ift.tt/2fkoylw
