A: You’re right! There is no reason to hide getting your period from your mom. Some moms are not always comfortable about talking their young daughters with these transitions. Sometimes it’s their own experience with this (maybe their mom did not discuss periods with them) that may hold them back, or possibly if they are religious, it is not something they feel they can talk about. Sometimes it is just a matter of a mom not knowing how to bring up the subject, so every girl should go to her mom to talk about this.
When you go through puberty, your feelings and way of thinking also changes. Some girls feel more mature and want to be more independent so they think that not telling their moms is a way of being independent but every step towards independence takes time and guidance and your mom is there to help you every step of the way.
