We’ve been in your situation. In fact, we’re in it again because daughter is pregnant again. All I can say is SWOT’s advice is right on the money. Your 28 year old daughter made a choice, now she has to deal with the consequences. Resist the urge to ride in to the rescue. At your age with serious health problems you’re not in a position to raise more kids. It’s not being selfish, it’s being realistic. She can either step up and do what she needs to do to raise the child (unlikely) or she won’t. That’s when it really gets tough. I plan on staying out of it, but if the child isn’t being taken care of, I’ll call CPS.
