Desirae, my personal opinion is that your nephew is NOT safe. If your mother is going through detox, she's got more than she can handle herself. She could have a moment of extreme impatience because she feels so bad. What of your nephew then?

The only way your nephew would be safe is if YOU had him 100% of the time... or CPS did an intervention. I'm sure that not even then, your sister would stop leaving that child with just anyone and stop partying. Even if she did stop, how would she react to the child? She would resent the baby for keeping her at home where she belongs.

That baby is not growing up grounded, feeling secure. Too many strangers in his life that suddenly get taken away from him at your sister's whim.

It really doesn't matter what your sister is doing or what your mother is or is not doing. What TRULY MATTERS is that baby boy! The most important consideration is that baby's welfare, not anyone else's feelings about it. WHAT IS IN THE BEST INTEREST OF THAT CHILD???

If you don't feel like you could take him full time, then it's time that he gets placed in a safe, stable environment.
