The 3 month old can not speak for herself. Be her advocate as she deserves a chance in life.
Did you see on the news a mom who just got arrested for breastfeeding her new born, because the mom had done coke and it went into the baby's system. The baby was lethargic and her eyes were rolling in the back of her head.
Please stick up for your precious neice. Maybe this is what it will take for her to get her act together.
