Awesome that you added skype! You are a good guy and that's really cool. I hope you skype with your daughter too when she's at her mom's.
You can beancount and worry about what's fair and how much contact with mom is excessive during "your" time, or you can just be the very best dad and do the kind thing sometimes and you will be so much more attractive, to your W and to anyone else. Good job today.
