We have shared DC and DH has 2 other DC (my DSC). We all get along fine. Summer holidays are approaching and DH is grumbling as I haven't booked time off work while he has DSC. I just don't see the need to really, DC is at nursery and it feels a little odd to me if the 4 of us all go on a day trip and leave DC out. AIBU? I suppose I could take a couple of days off and go for a meal or shopping but I don't like the idea of all of us being miles away and leaving DC at nursery. Am I being ridiculous?
