Am I enabling my daughter?

Ok, I admit upfront that I love my granddaughter and this year due to a layoff, I have had the opportunity to really share some time with her. My daughter asked me before the beginning of the school year if I could help her out by picking up my 10 year old granddaughter from school. I go to school from 7:45 - 11:45 Mon - Fri. I am in training for becoming a medical istant. My granddaughter gets out at 2:40. So I'm thinking this will be great for both my daughter and I - I get to spend some quality time with my granddaughter (we even do home work together!) and I save my daughter the expense of having to pay for after school day care (she's a single mom). I thought this would be a great arrangement and my daughter would finally be able to get herself to a point where she feels comfortable financially. What it's done is caused her to spend more money. She has dinner with us frequently (which is of my doing - not hers). I was hoping she would be able to save some money for some security but it just hasn't happened. She goes on camping trips with her boyfriend (and yes - they take the kids - he has a son from a previous relationship) but she ends up paying for the entire trip! My daughter has her own apartment and a great job. This has become a sore spot for my husband and me because he feels she's taking advantage of me. He pointed out that she told him she would purchase fire wood every 2 weeks (on her payday) for us, which I thought was very generous of her, but when he asked her for some wood, she said she couldn't pick it up until she got paid. The wood is $25. Since she wasn't due to pick it up before then, I saw no problem with (we had plenty of wood), but my husband was extremely disappointed that she didn't even have $25 since she was saving well over $300 a month for me picking my granddaughter up. Any Thoughts?
