6 month old hates I.L's house! Help!

[YouAreMySunshineMyOnlySunshine]

Hi all. Just wanted some advice or wondered if you have experienced a similar situation.
My 6 month old dd has been really upset every time I take her to my in laws.

I take her around at least twice a week or dh does and she's ok for 5 mins, then has a complete breakdown and only I can settle her.

She's fine with my parents at their house, and she seems ok with the inlaws when they come to ours.

I really can't put my finger on anything that my upset her in their house. She used to be ok around there when younger.

I feel really bad for the IL's, they are lovely people and I think mil is getting upset and a complex about it. Problem is I'm meant to be leaving dd with her 2 whole days a week when I return to work in march and don't want wither upset.
Dd has always been really attached to me, she's only just started being more comfy with her daddy in the last few weeks.
Any advice would be fab.

just grit teeth and get on with it, short vists often

the stranger danger/sep anxiety can go on for months, is perfectly normal so just go with the flow

it's not their house per se, more of being in unfamiliar surroundings IYSWIM

(I take it you've been through all the pitfalls that can occur when faaaamily provide childcare, blah blah blah?)

She's my first so alien to most things baby. I suppose we'll just have to all women up and deal with it. I'll try more visits around her work shifts. She's BF and won't take a bottle or cup either so I guess I'm anxious that this is gonna add to these existing issues whilst she's there.

Don't think mil has helped situation really as she offered a ton of help pre birth (one of these I really really want a grandchild now types) then never delivered and I felt cheeky asking (usually if I did she'd have things on).

And dh works away all week so I think she's just extra clingy.
