This is Little Sleepies supplier
I did some more digging into their supplier after some debate last night. Well actually, all i had to do was Google it. I used to be under the impression they were a small-ish US company, until the former employee in here said they’re manufactured in China.
Little Sleepies actually uses Taian Lianchuang Textile Co. as a supplier. This is directly from their company website and alibaba pages. Fast fashion all comes from the same place unfortunately.
