I'm going insane. With this whole DFCS issue with my 2 year old, I can't stop thinking about what to do with my newborn when she arrives in the next 18 weeks. ): I'm not with her dad, and he lives 400 miles away and right now we can't be around my 2 year old's dad because of the lies that were told about him. I was gonna give the baby to her dad because I wasn't in any position to have a baby right now and he has been wanting kids forever. But now I'm at the point where I just can't see myself giving her up after almost losing my 2 year old with this DFCS bullshit. But I can't keep her from him and make life hell for him to see his daughter. I just don't know what to do or what to think.
