Oh, getting sitting time isn't so much the issue. Our older ones will watch the younger ones for $$ and would even do it on a weekly basis. The problem is that the older ones need so much tutoring, then there are activities, then commutes etc... It sounds like excuse making but it really isn't. The kids in the house aren't the only kids either. We also have grown foster kids whom we cook Sunday dinner for etc...
All that being said...H and I COULD HAVE worked out going to the dance class, there might have even been a way to work out going to the Italian class together BUT he just didn't care enough about whether or not we could do it together to talk about the logistic. He didn't talk about anything. He just chose the Italian over the dance. He just picked the one activity that I couldn't do over the one that I could. He just chose the one that he wanted over the one we had discussed twice in the past. See what I'm saying?
