My older daughter is 8, nearly 9 and has just started puberty. (Just breast buds and mood changes so far) my problem is that my husband-not her bio dad- doesn't seem to accept that she's growing up. He's been part of our family since she was 6 and still sees her as a little girl. The main problem I've had is him going into her room without knocking first. I call out when I'm entering, and I've asked my other daughter aged 6 to do the same. I've also asked my husband to do this, but he doesn't. How do I discuss it with him?
