Prepare yourself for splitting the kids. It's hard. Imagine a house full of kids and noise and the sounds of busyness - life.
Contrast to days alone with yourself. Counting down the days until you get to see them. Maybe with 3, you can space them differently. Get as much time as you can if it comes to D. You won't regret that and neither will the kids.
The good parts are you have time to do things now and time to think.
It still hurts to return my daughters after a year and a half of this BS.
