Is there a way to tell a child their other parent is wrong?

My son is just over 2 years old but I've been having premonitions of the future based on the behavior of my wife, his birth mother.In short, she is disengaged from him that would almost seem "acceptable" if she was the father. For example, since birth, she's gotten up with him (he wakes between 5-6am) maybe 5 times, feeds him a meal from preparation to cleanup maybe once a month, no daily daycare preparation, etc. The most time she spends with him is the hour or two after she comes home from work (she doesn't have a demanding job). After he goes to bed at 8, I follow around 9 (to wake up with him) and she stays up until 1-2 in the morning watching TV. I've explained to her my concern that she's repeating a pattern from her family with this disengagement/self-centeredness and her response has been a combination of both "Yes that's the amount I'm willing to dedicate to him/you're the one who wanted kids."Given that background, her reaction to him going through typical two year old behaviors is really off. Her reactions seem are somewhat more appropriate for a much older child and when I try to explain that what he's doing is normal, she refuses to accept it. She and her family also feels that behaviors are not learned but passed genetically so I think she has unfounded shame that she's passed something onto him.I'm fully anticipating that throughout his life, I'm going to find myself in a position to explain to him, "Your mother is wrong". I think right now its a little early but I see it on the horizon. Is there an acceptable way to do this? Age dependent? via /r/Parenting http://ift.tt/2Gcc0Ja
