Daughter started her period

Amanda • I'm married to a wonderful man, David. I have 3 beautiful stepdaughters who I love very much. We're TTC our first child together so lets hope for baby dust! 💕😘👶💙💖

Last night, in the middle of the night my 11 year old woke me up because she was bleeding..yes, she knew what it was because I sat her down and talked to her about as I had a hunch she was going to start within the year and asked her to tell me when she did.

I'm so not ready for this, she's growing up so fast :(

Any advice would be greatly appreciated ladies, such as can I give her model incase she experiences cramps or just stick with Tylenol?
