I love having my 4 month old granddaughter with me. But, I don't want her to stay the night unless dh is home! LOL He just loves sitting and playing with her, I do too, but after raising 3 kids, I am tired!
My dh is a truck driver so he missed out on a lot with our kids. We are only in our early 40's, so it isn't too that we are too old to watch her, but, for me, it is work!
My son works full time, my dil is a stay at home mom. We started watching the baby over night when she was 2 weeks old. The kids said "they needed a break". Ok, but then it was turning into every week-end! That is the only time I get to see dh.
I have had to put my foot down a bit. I will take here when I want to, not when they say. I raised 3 kids witn NO breaks! I was feeling used.
So, I still have time to do what I want and I watch her when I want and not when they say. I like it better this way.
