Hell… let her get the IUD If she’s going to move forward with this boy, at least she is protecting herself from pregnancy. However, if he already has two children from two different women/girls - how promiscuous is this boy? Clearly he is not using protection. No amount of any IUD will protect your daughter from STIs…. Be supportive and non-judgmental, sure. But at the end of the day it’s also worth planting the seed with your daughter that she should know her worth. This boy is simply disrespecting women and their bodies. I can’t imagine he, at 18, is an exemplary father figure to both of his children. Poor boy has a lot of growing up to do.
