Dear Reader,
Put yourself in the situation...
1. Would you rather have one main home, or two places that you have to juggle between? (remember that you are an adult though, making a conscious decision because you have a choice)
2. Have you even asked the child[ren]?

Do Children Benefit from Equal Custody?
Alternating Custody
The idea of rotating custody or anything similar to that is just stupid. This isn't to appease anyone's ego, remember that you are raising a human being so that he/she can become a successful adult. Children thrive in a nurturing, stable environment with their primary caretakers. Children need secure attachments. Period.
Anything else is just experimentation at the expense of the child.
