Kimmy, I don't think that I am such an oddball. I take kids to play with every chance I can. There must be others like that? A surrogate aunt who could slowly develop a relationship and start taking baby overnight sometimes. Also, just my opinion but I think calling your mother to see if she is picking up the kiddo is giving your power away. I also would suspect her of emotionally messing with the poor little guy. All of that said, you have custody, if she calls and says she wants to see him fine but don't call her. Is there a church you are involved with? If not it doesn't matter, pick a church or churches and have the clergy announce that there is a little guy in need of an Aunt and or Uncle, or grandma, and make sure he/she has people get back to him/her to give you names. Check them out, check out references and such. There may be a parent child center or other similar agency near you who could recruit the volunteer and do background checks.

I think that the thought of exposing my kids to The Mother is too much for me. They were not raised to understand that cruelty.

I wish you well and heck, I don't care if it's appropriate, can we get a gremlin to knock her down the stairs?
