Only the female flowers are relevant for THC. And THC has no smell.
Everything else of the plant is used further for other things and could in my opinion smell like weed.
So, when I look at it this way, hemp-like materials could be present in the stuffed animals or the mattress. There are even infant starter kits like fleece pads, diapers, etc., partly made from hemp. The curtain could also be made of hemp. Whether it then smells like weed, for example in a damp state, I don’t know.
Also, the plants in the pots in front of the window could, if touched or if the wind is right, smell hemp-like. That’s why I said to rub the leaves between your fingers.
The resinous trees, meaning the resin, could also emit a similar smell.
I think the answers here should reassure you about the smell.
And if you google: the internet is full of things made from hemp and people who smell something similar without consuming weed.
