Our 4yr old owns my wife. Help!

Hi guys,My wife and I have a 4yr daughter who is a very happy child. She's very smart, socially great, and an all around amazing little girl. But, in the past 6 months I've noticed that she's very different around me when we are alone than she is when her Mom and I are with her together.For example, if Mom had to work late and it was just daughter and I, she would eat her dinner without needing any help, not complaining, and she would eat pretty much whatever I made her.When we eat together as a family, all of a sudden she's doesnt want to eat her food, she complains, and my wife has to make up some type of game to get her to eat her food, and basically feed her. I've seen my wife make our daughter 3 different dinners in the same night just because my daughter said he didn't like what we were having. My Mom would've NEVER done that for me, dinner was what we were having, or I could have a PB&J..Our daughter was a champ at potty training, and I don't think has ever had an accident. Now, all of a sudden she requests my wife to accompany her to the restroom for her to be able to poop (she'll go pee by herself fine). She poops fine at school alone. And it was just her and I home together, she'd go poop alone just fine.I just feel like she's totally controlling my wife, and I can also tell it's wearing on my wife. And me stepping in doesn't help, if Mom is also there, she'll still do the behaviors. Whenever I make a comment about our daughter not needing that "help" when it's just her and I, it pisses my wife off and she takes it like I'm saying she's not doing a good job, etc.My wife does the lions share of the tooth brushing, dressing, hair brushing duties with our daughter and we both interact and play with her equally, but I want to figure out why my daughter is doing this.I feel like maybe I just expect more from her when it's just us alone, and she delivers with no issues.. Introduce Mom in the equation and all of a sudden she needs help with everything.Can anyone offer any advice on how we can correct this? via /r/Parenting http://ift.tt/2BKQzPH
