My ex-wife of two years has moved to another state and has custody of our 6 year old son.
She consistantly uses him for delivering phone messages concerning the adult problems she and I had experienced during our marriage and other matters of adult issues that a small boy has no business dealing with.
She also gives him a laxitive called glycolax due to his bowel movement problems.
When he comes for visitation he has problems relieving himself and becomes impacted. She then instructs me to double the dose which results in a multiple uncontrollable loose bowel movements which results in my inability to work and care for him. I had to return him last summer due to this condition.
This Christmas he again had the bowel movement problem and I asked him what his mother did when he would not go. He said she gave him supositories but that she did not pack any.
I called and asked her what I should do since he had not gone in three days. she said I should double the dose of Glycolax. I asked her about the supositories and she acted surprised and I then asked her what they were called. She told me.
I felt that she was setting me up for another incident like had happened on the previous visitation.
My girlfriend of 1 year is a doctor and very intelligent women and a great mother. She has two daughters away at college.
She recently moved in with me. My ex had my son call me and tell me that "I was sleeping with my girlfirend and that mommy was mad".
Is that child abuse?

I am not positive if this is considered child abuse. It probably depends on your state. I can say that this is definately NOT RIGHT!! We went through something similar with my stepson and our attorney was telling us not to say anything but it got to a point that we had to. His mother would say awful, UNTRUE things about the sitation and my husband and I. Instead of my 11 year old stepson being able to decipher this himself it ended up building in his little head. He didn't know what to do with this information other than to not like his dad and I. By us keeping our mouths shut it did more harm than anything else.

My point here is that NO CHILD should be put between his parents. As you said, these are issues that are not meant for a child of his age. If I were you I would seek an attorney and, as long as you want it, request a modification of custody. It sounds like the child would be much better off with you. You will need to make sure you have documented times that she has put the child in the middle. I would also document these health issues that your child has. I am no doctor but I know that taking laxatives on a regular basis is not a good thing and you need to find out if this "problem" that your child has is documented in his medical records. Contrary to what your ex may tell you, she cannot keep you from looking at your child's medical records or contacting his/her physician with concerns...unless there has been a court order. Please do not wait too long to act on this. Everytime your ex puts your child in this situation she is causing long term damage.

Good luck to you!!!

zI would not call it child abuse but it may not be the best parenting. You should talk to her about this and set up a way you both can communicate so the child is not in the middle.

What your ex is doing is known as parental alienation. Petition the court to have the child, yourself and your ex evaluated by a psychologist or psychiatrist. He will then issue a report to the court of his findings.
