Should I let my daughter spend extra time with her dad? I would like some advice please. My daughter 15, is at dads place for week with 2 brothers. They come back to me on friday. At dads place he lives with girlfriend and her daughter. My daughter rings to ask if she can go to birthday party at dads place on saturday for the girlfriends daughter. She is supposed to be with me during that time. My opinion is that they all live together for the week and also go to same school. So therefore had all week to celebrate the birthday and spend time together. I don’t feel its fair to take part of my weekend to have more time with dad at the party. What do others think?
