My parents and sister live a couple of hours away from me and my husband so we don't get to spend much time with them or they with our child who is now 5.
They are coming up tomorrow and have arranged to take me, my sister, my nephew and my DC out for the day to an amusement park. We rarely do anything as a family so looking forward to it.
The thing is my husbands older two children are with us tomorrow (I'm off and DH is working from home in the morning but off in the afternoon). This is outside of their normal time with us due to the school holidays so my parents didn't know when they booked to come but in any event they would prefer it to be just us anyway as they don't get much time with our child and my SC can be quite full on and argumentative.
DH is pulling his face that I don't want to or haven't offered to take SC and has said he can work flex in the evening instead so he can come too with them. I've told him no and to just let my parents spend a day with me and our child.
Aibu not inviting SC and DH along? For context they are 9 (SD) and 11 (SS). Our child is 5 and my nephew is 8.
My parents and sister will be coming back to ours after we've been out to have a cup of tea and stuff and say hello before heading home so will see them later on.
