The Kardashian retail empire is growing so rapidly, it's almost impossible to catch up. The latest expansion to the Kardashian fashion empire is the Kardashian Kids toddler line which will be available in stores starting Sept. 19, 2014 exclusively through "Babies R Us."

Sisters Kourtney, Kim and Khloe started out with retail fashion boutique DASH which now has several branches across the United States. The latest branch just opened this summer in The Hamptons. With the success of the retail stores, the sisters eventually launched the Kardashian Kollection, a fashion line released in partnership with SEARS Department Store and now with Lipsy. After the birth of Kourtney's kids Mason and Penelope as well as Kim's baby North, they teamed up with world renowned children's wear brand "Babies R Us" for the release of Kardashian Kids Kollection, a line of clothing and accessories for babies up to 24 months old.

With Mason now 4 and Penelope now 2, the Kardashian Kids collection is expanding into toddler fashions. Kourtney Kardashian announced the good news in her Instagram account by posting a photo featuring the latest collection modelled by two toddler girls. She captioned the photo: "We will be offering @kardashiankids for toddlers now too up to size 5T starting September 19 @babiesrus!

The new line reflects prints and designs already featured in the initial Kardashian Kids line. Leopard prints as well as light flowery prints are featured in the collection as well as edgy faux leather items. Khloe also posted a photo featuring the new toddler collection on her own Instagram account. She said: "So excited to bring you our @kardashiankids toddlers line this month! In sizes up to 5T and at all @babiesrus stores on September 19th!!! You requested and we made it happen"

Baby North West, Kim Kardashian's daughter with rapper Kanye West also made an appearance in the Kardashian Kids Instagram site where she is seen in a photo wearing a tiny leather skirt that's part of the collection. North just turned a year old and is now the only Kardashian baby still small enough for the original collection. She will soon be joined by Kourtney's third child who is due in December. Penelope and Mason Disick can now continue to enjoy wearing the Kardashian Kids designs through the toddler line.
