Iam an aunt to a 4 year old boy my sister was in prison for about 2 1/2 years my mother took over rights to my nephew while my sister was in prison.My nephew has been with my mom since he was 6 months old he is now 4 .when my sis got out of prison just about 1 1/2 month ago.she took my nephew, my mothers grandbaby, away a week ago is there anything we can do she won't let my mom see him or talk to him please somebody help me or rather help my nephew please?!

Try and talk to the mom of the child and make up. What happened to cause them to not let them see the child.
What type of legal paper work was filed, was there temp custody orderr in place, was it changed in court??
