Thank you so much for answering! I still don't understand which tests are needed and what tags and what should be on the tags. :) I feel so stupid but it's really not understandable on the official websites.
Do you have any idea of the costs of testing? If it's loads of money it's not worth to start selling it on Etsy I suppose because I'm in the price range of $15 per item ^_^
Every test needs to be on that specific fabric that one uses for the item right?
In Dutch we call it a 'trappelzak', and it's for sleeping but also in strollers etc.
Here's an example:

What I meant with the shops is: if people sell children's clothing that is approved, it should be mentioned that it is tested/labeled/approved by CPSIA right? I see so many shops that don't have that info in the listings or shop info.
