Sometimes I feel so sorry for SS13
We took all the kids and SS13's two cousins out to the mountains yesterday and did some hiking, sightseeing, rock climbing (OK, on a very small scale, but they gotta start somewhere).
Halfway through the day, SS13 tells DH how much he loves it and the entire day. He does this often when we do family outings. We are a pretty busy family as we have ss13 full time and my BD12, BS10 and BS8 about 60%+ of the time, plus we try to go to their games even when they're not with us.
SS13 never got the benefit of really doing "family" things. When we've all gone out to dinner to celebrate a birthday, he tells DH how much he likes being a family. When we all pile in the car for an impromptu day out, he'll let him know how much fun he's having.
I know that my influence on the kid is ABSOLUTELY one of the best things to ever happen to him (and I know he knows that too), it's just difficult for him to see this all the time - especially when BM tells him that his dad never spends any time alone with him, that DH and I treat my Bios better, blah, blah, blah.
But, it's times like these when I know I'm doing a good thing.
