Wow, listening to your 7 year old is "coddling" them? Really?
You know, it may just be the MLC. When my W went into her MLC, she seemed to always put off our D's when they wanted her. She was always "too busy" or "too tired". I actually thought it was more about her depression than MLC but when I look back, she just was so busy doing for herself and just didn't want to be bothered. A 7 year old will be in bed early enough that you should be able to have plenty of "adult time". It may be that your H was raised this way and it could very well be one reason for his MLC. He never was "heard" and felt that he wasn't "important" enough. I'm not one of those crazy "helicopter" parents by any means. Kids need to take responsibility for their actions and be allowed to "fail" at times. Constantly "protecting" them IS coddling. But to be available to listen to them when they need you isn't anything but what a parent should do.
Don't let you H's MLC fogged ideas make you question yourself when it comes to your S. Sounds to me like you are being a really good parent!
