3.5 year old keeps telling my wife she hates her

I work full time & we’re lucky enough to have my wife staying home with 3.5 year old daughter and 1.5 year old son. My daughter seems to really always like the person she’s around until someone else comes along. For instance, she’s usually pretty nice to my wife till I get home. Then she’s all about me in the evenings and on the weekend. She’ll only want me to do things for her so if my wife comes over to unbuckle her from car seat or get her something or whatever my daughter will say “no I want daddy to do it, I want daddy to do it.” My wife seems hurt by this a lot of the time. I consistently tell her she needs to be nice to her mother. My daughter will then do the same thing to me if someone new is around. I’ll take her by my parents in the morning on the weekend and once grandma is around now I’ll be scoffed at. Now she wants gramma to do everything and she tells me to leave. I’ll go run errands usually for a bit so the grandparents can have some time with the kids. This doesn’t bother me as much as she bother’s my wife. Now yesterday me the wife and the 2 kids were at a mall and when we’re getting back in the car my wife is buckling her in the car seat and I hear her tell my wife “I hate you mommy.” My wife is devastated by this. Does anyone have any advice on how to deal with this? My wife and daughter not getting along is affecting everything for us at home. I don’t picture this getting better as time progresses into the teenage years, it’s really got my wife upset. Any insight would be appreciated. via /r/Parenting http://ift.tt/2f0qEK5
