My wife doesn't want her teenage stepdaughters to come with us and baby to a concert for babies. I only have them every other weekend (Fri-Mon) and half the holidays, and I don't want to exclude any of my kids from activities. But she insists on arranging the baby concert on a weekend when her stepdaughters are here and doesn't want them to come. Is that fair?
PS: she says that weekend is at the end of their 2 weeks holidays. The first week I'm going skiing with the girls, but not the baby nor the wife. But neither the wife nor the baby can ski!
