My , not having done it... but from people I speak to who have, you need to be super duper organised! You need to have a reasonably good relationship with the father or at the very least have an open line of communication and problem solving skills.

As for the effect on the children, it varies as kids are all different and their ability to cope varies. The younger ones have found it more difficult usually, compared to the elder who are able to comprehend what is going on, as the younger miss mummy.

It also depends on how you plan to split the 50/50, I know some who have gone week about which has been too difficult on the children, and others who have gone 4 on, 3 off etc, which works for them and vice versa.

Would you be able to have a trial period to see how your individual children handle the change?
