My mom believes that per tradition the brides family pays the majority of the wedding. So she has stepped up and paid for almost everything. My mom has even offered to pay for the Rehearsal dinner but we are going to pay for that. How do we politely thank my mom for everything that she has done without offending my fiancés parents. We understand that they are in no way obligated to help us with our wedding and we are not upset. At the same time we don't want my mom to feel like she isn't appreciated. Help please.
