‘Creepy Crawlers Easy Grip Crawl Suit’ - did anyone buy any of these?

I can’t seem to find anywhere that sells any other size than 6-9 months And seems it’s online baby shops that sell them. Can’t seem to find an official website for the makers of them? There’s som 18-24 month ones for sale on eBay but looks like maybe a company made them and then stopped? Anyone know? 🤷‍♀️ My LO had hip dysplacia so is late in crawling and the knee pads you can buy on Amazon etc that have grip are rubbish for her. Am suprised not many places produce these types of grips body suits. If you know of any brands pls could you share. Thanks a lot
