I'm sure I could acknowledge her "baby steps" more often, but it's another fine line with her...does my acknowledgement sound patronizing? Geeze, my head hurts. As far as helping with the baby, I usually am responsible for picking DD up from the sitter and taking her home, which I do at about 5pm. W doesn't get home until 7, so DD and I do some cleaning, laundry, cooking, playing until W gets home. And whenever W can't drop DD off in the morning due to work/conflicts, I will take care of that, too. No, I don't think it's a problem there.
Regarding her weirdness on how to be approached when ML, yes, I've talked to her about it, but not lately, since I haven't really approached her for that reason for months.
I've done what I can do. I gave her the SSM book, which she has read 31 pages of. I guess I just have to be patient, speak my mind when I need to, and love her.
