Hello from Amazon Selling Partner Support,
 
I understand that you want to know why your ASINs B0D76K7LSV, B0D75VBH85 and B0D5L7L48X have been categorized as children products and you want to understand what violation is applied on your ASINs. 
 
Upon thorough investigation on your concern, we can see that you'll be needing to submit an appeal and documents in order to reinstate your listing. To proceed, you must provide all the required documents for the ASIN. Partial document submissions are not permitted and will be rejected.
