At the moment me and my ex-p live very close to each other and he sees dd (2yo) about 2/3 times a week. It is a very casual arrangement though, we generally just decide at the start of the week when he will have her and it varies week by week.
For a few reasons I am considering moving about 200 miles away (family support, cheaper, I don't like where I live). Ex-p would obviously miss dd but is happy for us to go as he knows it would make our lives much better. The place I would be is very easy to drive to and there are also a lot of trains/busses.
If you live far away from your DC's dad how does contact work? Me and my ex get on well so I would happily have him staying in my house or stay at his with dd.
