Toddler's weekly sweet treats

Hi there. Out of curiosity how much does your toddler consume of sweet treats per week? In my opinion it should be at least once every 2 weeks for higher sugar content treats. My 4 year old seems to have them nearly every other day with school meals, they will also send some home. My partner feels that's okay in moderation but, I am usually left having to negotiate. I think the frequency is leading to very poor habits and he is starting to reject healthier options. There is no gap in between celebrations and holidays. We also tend to get quite an amount from family and I have to throw some out from time to time but it's a battle as he knows exactly what we have so has to have some before disposal. Would love to hear how you manage to control it.
