"Stormi cannot get enough of the new baby," an insider told Us Weekly. "Stormi has been helping out and is so excited about being a big sister."
Kylie, Stormi and Travis have "all been non-stop smiling" since the new addition joined the family, the insider added.
The coparents are very "hands on" and focusing all "their time and energy on their new baby," the source reportedly explained. Luckily for the couple, the newborn has apparently been a "really good boy" for his parents and has been "sleeping overnight."
Only close friends and family have met the new baby and know his name, the source squealed, noting that the Kylie Cosmetics founder will "release his name when she’s ready."
Another insider also noted Stormi has been "very gentle" with her new sibling, OK! reported. "She is fascinated by her little brother and has been able to hold him."
While the reality star has not yet shared her son's name, fans have been trying to guess what it may be. After Kim Kardashian, Kris Jenner, Stassie Karanikolaou and her makeup artist Ariel Tejada made references to angels when commenting on her announcement post, fans speculated the baby could be named Angel. Other popular guesses include Gabriel, Valentine and Rainbow.
