Thing is though... if they don't want to be involved with the child, it's probably better for the child if they're NOT involved.
That's the way I see it with my DGD anyway.
My ex-dil never even wanted me to see my DGD until the divorce. Then ds got 6 weeks of custody last summer - and they lived with me. Then ex-dil had her, and ds had weekends. Well, soon the ex was asking if we could keep the baby an extra day an extra 2 days. We ended up having here 4 days a week all fall, all winter.
Ds complained. Dh complained. It was tough on me because ds was working those 2 extra days so I was the one watching this baby. There were weeks when I had to say no, I couldn't do it because I had my ESIs and my arms were going out.
But any time I could, I did it.
I didn't do it as a favor to the ex, my son or anybody else - I did it for my DGD. This lil girl needed somebody.
her other grandma *needed to sleep in* - she's 10 yrs younger than me.
Tell ya what, she loves me, I adore her. It was worth it and I'd do it all again if it killed me.
I do it because I want to be there and I'm good for her. And this child is the best thing that ever happened to me.
