Some of my family live abroad and before I met DH I would often go and visit them throughout the year for a week or two and even the off long weekend. Since being with DH, I haven't been as much but have still spent the odd 5 days out there / long weekend on my own.
DH works long hours. He is self employed and rarely has time to take a decent break. We haven't been on holiday together in years.
We now have a child together. DH has 2 children from his previous relationship who are older (one just turning 10 shortly and the other is 12) and in school.
Obviously right now this isn't an issue due to Covid but talking about the future, I cannot afford to pay for all of the children to go with me during the school holidays. Due to the size of my families house, all of us going would mean having to pay for accomodation as we couldn't all fit in my families home and DH can't/won't take the time off to come with us anyway.
It's never been an issue as I've always gone on my own to see them and DH has stayed here with DSC (he's only ever come out with me once for a few days when we didn't have DSC).
As our joint DC isn't in school yet, WIBU to just carry on doing what I do and take my DC over there for the odd break throughout the year on my own when it's cheaper and DH stay here with DSC? It obviously may look like my DC is getting holidays and DSC aren't but it is also about seeing and keeping in touch with family and doing so whilst it's still cheap enough whilst my DC isn't tied to schools holidays.
I'd be more than happy to go on a joint holiday if DH had the time and he paid for the majority but unfortunately I can't afford to take them on my own and I'm not sure I'd want to take all of them without DH!
Fwiw, these are my grandparents. They have visited us in the UK before so DSC have met them but not very often.
