in past few days I heard that many girls kids having age between 9 to 11 is having their periods start. and at that age they are too small to understand this... they are only 3/4 class. why this so.? what all food we need to avoid not to give them especially in summer season. ? I also have a daughter at age of 10 and now I am worried after hearing all this things. please suggest what I need to do and not to do?
