The decision to have a mundan ceremony for your three-year-old daughter should be carefully considered and should prioritize her well-being and comfort. Mundan is a traditional head-shaving ceremony that is often performed in some cultures for various reasons, including religious or cultural beliefs.
If your daughter is expressing strong resistance or fear towards the ceremony, it's essential to respect her feelings and wishes as much as possible. Forcing her to go through a ceremony against her will could be distressing and potentially create a negative association with cultural or religious practices.
Instead, you should try to have open and honest communication with your in-laws about your daughter's feelings. Explain the situation and express your concerns. It's essential to foster understanding and find a solution that respects your daughter's feelings while also considering the cultural significance for your in-laws.
If there is a possibility to find a compromise or alternative way to honor the tradition that is more comfortable for your daughter, it would be a better approach. Ultimately, the well-being and emotional comfort of your child should be the top priority. If there are strong objections, you might want to consider seeking advice from a family counselor or mediator who can help facilitate the conversation between you and your in-laws.
