I haven’t checked her chart and will advise u the same – not to share her details with anyone. She is a kid. The more u think “shashti tithi pe mundan hua islye she is aggressive, the more she will become cranky”. You need to understand where the mind goes, energy flows. Give her some time – almost every kid is like that. There are phases a kid goes thru, even a grown up as well. If that’s the case then what would u say about people born on Shashti tithi. Use astrology only when situation gets totally out of control. Have some patience, she will be fine and let her life and karma unfold naturally.

You can redo mundan on good muhurat
