My 7 yo is very frustrated with me and doesn't know how to discuss her issues.

Last night, my daughter walked up to me an gave me a little gift (sidewalk chalk in an envelope). She explained with enthusiasm where she found it and I told her we would play with it tomorrow. Very shortly afterwards, she had been playing on her keyboard and mic toy for a bit. She then wanted to show me what she recorded as a song for me. It was a bit indistinguishable, but she explained that she's singing "i hate you mommy".I understand her outlet to express her frustration towards me is good. I'm glad she can use something. Though her song-making is very rare, so I dont see this as a continuing thing. But I was trying to have her explain why she hates me. She later admitted one of many things I do, that she doesnt like. But it was hard for her to share anything else she didnt like about me.Between her father and I, I am the enforcer. I try to make sure there's consistency and order. I've become way more lenient over time. Only, because my half daughter is a snobby teen that walks all over her dad to get what she wants, and I can't just exclude my daughter from having the same.Long story short, I don't know how to have my 7 yo open up to me so we can discuss things. She's made it very clear that Daddy is the fun parent. And I've nagged him and the family like crazy to not let things get out of hand. What do I do? via /r/Parenting http://ift.tt/2amXP4Z
