AIBU to tell PIL to keep DC Christmas presents at their house?

[Abilouise]

I have 2 DC, aged 5years old and 13months old. I had to downsize from a spacious 3 bedroom house to a much smaller 2 bedroom flat. DC already have loads of toys and play things. Me and DH stuck to a budget of £100 per child and we managed to get quite about 5 things per child which is only going to add to their toy pile. I've tried having a clear out but they play with quite a lot (especially my 5 year old) and a majority were expensive gifts from PIL so we wanted to keep them. we have asked PIL kindly not to buy DC so many gifts for birthdays and Christmas etc but they don't listen. We are incredibly grateful for every gift they buy DC but we simply don't have anywhere to put any of it.

AIBU to ask if they can keep this year's Christmas presents at their house? They have a twin spare bedroom which is for anyone but only really used for DC when they sleep round. They have toy boxes and clothes and quite a lot of things there already for DC that they bought especially for their place. I don't want to seem like I'm being ungreatful or like I'm taking the p* and using their house as storage.

We “rotate” toys between ours and Pils so that DD “has toys to play with at both houses and doesn’t get bored with them”.
Essentially it’s a polite way of saying that if they buy her something biggish then an equal size toy goes to their house to play with when we go there; suspect it’ll get harder as she gains more preference over toys but it works now

I think that's fair enough, especially if you visit quite often.

For their last birthday I asked my parents for a summer pass to the local soft play which meant that we didn't have more presents, so maybe they would consider something like that?

Thank you both :)

YANBU- if you frame it as asking them to get them a few things specifically to keep at their house they’ll be able to make any decisions based on that, rather than choosing something like a toy kitchen and then being put out that they have to store it themselves!

Me or DH don't get a say in what PIL buy DC for Christmas because PIL (MIL in particular) likes to keep it a suprise for us all. DSIL has said they have started buying already. They have already bought 5 build a bears for each child and a ride along truck for DD and a workshop thing for DD. DSIL wasn't supposed to tell me but she's only 14 and can't keep a secret to save her life lol, she just come out with it when we were talking about Christmas.

You need to have a talk or get your DH to have a talk about space. Try to not to hurt their feelings, but maybe suggest a garden/outside to keep at their house, like a swing or a slide - it can be a joint present that will last for years.
