this is just me being nosey...but wouldn't it be in OP's best interest to not commit to a visitation plan? no matter what, she's mom. if grandparents were so asanine to keep the child to gain custody, wouldn't mom have the ability to file criminal charges since grandparents don't have rights for custody? as mom, she doesn't need paperwork to demand her child back, right?
Personally I agree with you Isabella. When you voluntarily give grandparents a set visitation schedule or court ordered visitation, you tend to set up a feeling of entitlement/rights. They tend to view themselves as replacing their child in the parental rights arena. If things don't go well or the child wants to spend less time with them, you then have a big problem.
Therefore I would not recommend committing to a visitation plan. I would encourage mom to provide visitation as long as its healthy, but committing to a "plan" is not a good idea...particularly a court ordered plan.
Its hard when your child dies and naturally you cling to any grandchildren. However, sometimes that "clinging" ends up not being healthy. You sometimes have a child who is beginning to heal, and then spends time with the grandparents and is a basket case again. The grandparent isn't moving on and subconciously does not want the child to move on either. They want/need someone to share their grief.
I have seen this happen many many many times. It also sometimes causes grandparents to lose perspective regarding the child's other parent, and to view them as unfit or not good enough and the grandparent feels that the child should live with them.
Therefore there are times when its necessary to temporarily distance the child from the grandparents for a while. However, if you already committed to a visitation plan, and its signed off on by a judge...you have a problem.
