Do you allow your toddlers to eat desserts or any sweets after every meal?

My 3-year old is used to eating desserts after every meal. He got it from me as I can't have a complete meal without dessert since I was a kid too. However, for my 1-year old, I plan to not her get used to it. I'm happy that her taste buds only know vegetables, fruits, oatmeal and some pastries for now.
