We are staying with PIL this Christmas with our DC aged 8 & 3. SIL has now decided to come too with her DC aged 10 & 7. We all get on pretty well although there can be tensions at times.
My family have always gone all out for Christmas whereas DH's family are quite low-key. DH and I tend to meet in the middle but still do more in terms of decs, food, presents etc than his family. Our DC have a Santa sack which usually has about 10 items around £1-£15. I love shopping for them, finding bargains (thanks Reastie et al) and have got lots ready already.
The last time we were all together at Christmas was about 4 years ago and the children were relatively young. SIL had bought two presents for her DC1 and one for her DC2 for their stockings. We toned down our stocking for DS and I bought a couple of stocking fillers for both families so it kind of evened things out. Still, SIL's DC1 did notice that my DS got more.
This year, it may be the last time my DS believes and it will be harder to tone down the presents without him noticing. I'm not sure if SIL's DC1 believes but she will definitely notice discrepancies. The children will be sharing a room too.
DH is going to message SIL to see what her plan is and he has suggested that we could tell the children that FC is leaving some presents at our house for when we get back on the 28th but I am worried that it will end up with my DC being disappointed or working out the truth at the wrong moment.
I feel like I am going to be railroaded into something I don't want but obviously I don't want my DNs to have their Christmas upset either. How would you handle it?
TLDR: two families staying together have different Santa expectations. How to handle without disappointing either set of children?
