My 14 year old daughter has been menstruating for about a year and is making the transition from napkins to tampons. She is using regular size tampons and keeps complaining that it's uncomfortable when she puts it in, even though she is flowing pretty heavy. Even after she has had it in for several hours she complains it uncomfortable. I don't remember having this much trouble transitioning from napkins to tampons and wonder if she is just uncomfortable with the idea of putting a tampon in or if there may be some thing else going on like maybe needing a smaller tampon. Are there smaller tampons on the market for younger girls?
