different traditions/budgets sharing Christmas

[WineOhWhy]

So we are hosting this CHristmas and have various family members attending including neices and nephews (who live in Spain). Our CHristmas traditions normally include:-
Christmas PJs/book/DVD on Chistmas Eve
Decent sized stocking of (wrapped) presents from FC - opened first thing
A family game from FC and a largeish present and maybe a couple of small ones from us, under the tree, opened after lunch.

DO you think I should let SIL know what we do so she can think about whether she wants to do CHristmas PJs etc, or do we just let them do their own thing in whatever way they want? I fear our kids may have more presents than their cousins partly becuase of budget and partly because they will be travelling from Spain so there will be logistical issues. Maybe, alternatively, we should rein in what our kids get so relatives don't feel uncomfortable (but on the other hand when they get back to Spain they will have the 3 Kings celebration which I understand also involves presents).

My instinct is to do what we normally do, but let SIL know (so that if, for example, they were going to get some PJs anyway she could decide whether to give to them on Christmas Eve), and using the 3 Kings thing as an explanation for differential presents, if it comes up? But I woudl hate to think of DN&Ns feeling disappointed on CHristmas Day becuase they have less than their cousins (and woudl hate BIL and SIL to fee they have to spend more on their DC than they might otherwise have done), so I thought I would canvas views. My DC are 7 and 8, and DN&Ns range form 6 to 11 (but 11 are all young for their age). Younger ones are on the cusp of not believing (or may not believe and simply not have confessed it yet), in case that makes a difference.

Anyone else who has had to deal with this type of thing?

I think your DCs are old enough to understand that they could wait for some of their gifts (FC didn't have enough room on the sleigh to bring them all at once)

I would talk to your SIL about it. When my children were younger we used to get together with all the family. All the children used to talk about what presents they had got the day before. They also used to bring some of them. My children had far more stocking presents then my sisters children and my brother and SIL used to spend far more on their children's main present then we did. None of this seemed to make any difference to any of the children.

Could you maybe offer to buy some bits for their children for stockings- maybe stuff from poundland, a little bag and items for the flight home - pens, notebooks, sweets etc, they have cheap stockings there too. Can explain to your children before that FC knows they are just visiting so gets them things they can take on the plane. I would talk to your SIL and she might want to prepare her children for the different traditions.

If you can afford it go to primark and get them all pjs
