You're right, I don't know why I'm being vague. I'm paranoid, but nobody else I know reads here.
It's my niece, she's 21 and had a baby WAY before she was emotionally ready. She's almost a year old, very tiny - she only feeds formula and resists giving her any kind of baby food because she doesn't want her to be a "chubby baby". The pediatrician told her she's not feeding her enough and gave her a recommended schedule, but she's still feeding her the same amounts as she was months ago. We had not seen her in a few months, but my Mom kept her yesterday and is so upset. She said when the baby stayed with her she was eating everything she gave her and was wanting more. She also mentioned she's very weak. My niece has had eating disorder problems since she was a tween, she's 5'10 or so and is under 100 pounds. She eats maybe a meal a day.
UGH. This is a horrible situation. I honestly don't feel like she's taking proper care of her and she is adamant that she's fine.
Now that I've written this out I've solved my dilemma. I'm calling. My gut is saying that someone needs to step in that's not family and evaluate the situation. If I'm wrong then I'm wrong.
