I'm so uncomfortable, I want to ask my wife what happened between her and our daughter.
Why are you uncomfortable about asking her what happened?
Our daughter acts very spoiled. I think she and my wife had a fight about it, but I'm not sure.
I understand your concern about your wife spoiling your daughter. Moms love their babies, which is good, but it's important to make rules and set boundaries as well.
I think my daughter may be so spoiled her behavior can't be modified.
You have to talk with your wife, even though it may be uncomfortable. The two of you need to communicate and be united about what is best for your daughter and her behavioral issues.
