I have 2 DC and my DP has 1, none together. We've had an awful year (as has everyone), but it's been especially bad as DP's child was diagnosed with a very serious illness last year. Thankfully after lots of treatment they are on the mend but it'll be a very long road ahead.
DP wanted to book annual leave over the summer hols the same time as me so that the kids will spend time together (they get on well). Not a problem in theory, and on one of the weeks we have booked a little break away in the UK. We both work full time.
The issue I have is that my DC have asked to do a few things in the summer that I know DP's DC won't be able to do due to their current physical condition. I've briefly mentioned this to DP and he said that it wouldn't be fair for his DC to miss out (but in turn that would mean mine do. DP wouldn't be going, just me).
I can't book any more leave so I'm now in a position where we have the exact same time off with the kids, but DP will get the hump if I take mine somewhere during that time if his DC isn't able to go to.
I hope I've explained that well enough. I feel stuck. I'm conscious of my step child's illness but I also don't want to disappoint my DC and am not sure what's best as whatever I do I will upset someone!
