i agree, if it is bad. I have been through 3 divorces in my near 10 years and niether were fun for me or the child...not to mention, due to the change in custody or the moving from one home to another by one parent or both, I also lost care all together eventually or part time care. That is something you need to consider too, are you ready to posibly lose that income. They may tell you they want their child to stay with you, but just as their marriage is ending, you never know the future. you should safe guard your finances and consider looking for a replacement. Not to mention, you are in the middle and will be in the middle as long as you are involved with the child. Unfortunately we can't fix everything for these little ones and you need to protect yourself and your business if you think things may get ugly. and unfortunately with divorce, they usually get bad before they get worse.
Not sure if you are in the states or canada, but i know in the states, you need a court order IF one parent doesn't want the child to go with another. IF their is no court order you have to release the child with either biological parent, that can be tough for you, if the Mom says "dad can't pick up" and Dad comes to pick up? you have to let the child go, unless you have it in writing from the courts that he may not have the child on such and such days. Then you will have the Mom breathing down your throat for letting the child go with Dad, and you have a mess on your hands. Not to mention, who will pay for care? there is always that battle that arises as well, Mom says Dad is to pay, Dad says Mom. you don't get pd. Yuck! I say you get out before it gets bad, who knows you could end up in court for one reason or another before the end! Find a replacement soon!
