Aww, Janet...this stinks on many levels. :sad:
There is no reason you should be put in the position to raise this baby, even though it's your granddaughter. It appears neither parent is very interested. I hate to say it, but contacting social services and possibly considering adoption out might do one of two things: 1) Shake the living daylights out of it's parents, or 2) give the baby a solid, secure, and happy home.
So sorry.
