I don't know what to do. All of a sudden my daughter doesn't want anyone but me. If someone tries to help her or pick her up or push the stroller or comfort her when she is hurt she screams "No, I want Mommy." People are taking it personally and they are starting to blame me. They keep complaining about Aria hating them. Meanwhile, I'm exhausted from juggling two kids on my own all the time. Any advice or help?
