hi, yes u should worry,
will that do any good, maybe not

I would worry if you think your daughter or boyfriend are abusive or neglecting your granddaughter in any way. Not everyone with bipolar is a bad parent. I am a mom of two (soon to be three,) and I do a good job. Sometimes I'm irritable but that's about it. I don't put my problems toward my kids or family as much as I can.
Unfortunately the only way you can force help on her is if she is a danger to herself or others. She has to want to be well. She's not crazy, she just has an illness, but she needs to realize that. Only she can seek help and take the help that is given. :(
