I’m not reading everything now but did you install vinyl in the children’s room? The plasticizers smell similar, the different times can, for example, come from sun exposure.
Yes, we installed vinyl but throughout the whole house. However, it only smells in that one room.
I don’t know why you even asked me for a detailed explanation if you then see a problem in my answers here.
I have no discrepancy with you, otherwise I wouldn’t have replied to you at all.
By the way, I don’t answer PMs if I don’t see a need for it.
Sorry for the off-topic.
So: take a look outside at the plants or, as says, at basket, sisal or something similar
What kind of plants are those? If I enter basket or sisal on Google, no plants come up
