When my ex and I separated 7 years ago my daughter was 5 weeks old - he didn't take her for any overnights until after a year when I stopped nursing. He did take her for a couple of hours here and there before that. He is now separated from his wife and they have an infant and they worked it out to where he does take her for overnights and she pumps. The courts typically look for different sexes and age groups to have their own rooms and the child support in Colorado is an automatic form that calculates the amount based on both parents' incomes and number of overnights. Half is very generous of you!! He'd be paying more. Hang in there it can be very overwhelming - I hope you have some support somewhere! (church, friends, family.....)
