I personally think that Eddioes mother is one of the more sympathetic parents.
I would rather have someone who cared too much and tried her best, albeit got it wrong, than the cold indifference of Bills parents or the downright evilness of Bev's father.
Sorry, I get that this is an old thread, but I wanted to chime in. Parental indifference can lead to a kid having to face down freakish monsters of all kinds without backup, but it does allow for something precious that Eddie never really had: sweet freedom. Maybe it's one of those if you never had it, you won't miss it kind of things, but I'll take independence over smothering any day.
