Okay so someone asked me to upload the childrens birth order awhile ago, and I haven't yet so I decided to put some of their info into here.

Basically when skeletons hold souls, it only takes 2-6 months depending on the amount of magic and the child themselves, so Sans can have multiple children in one year. Also the creepypasta pounce on him like rabbits so yeah

Jans Child: COLE: 16 years old. 

Jackans: ADDY: 10 years old. 

Sing: BEAN: 17 years old, the "oldest". When Sans brought up having children with the others Laughing Jack picked him up and ran away with him because he wanted Sans first, thus Bean is the first child. 

Ends: SILKY: Technically is younger but she ages faster, looks around 18-19. 

Sandor: BOBO: Same as Silky, looks around 18-19. 

Sasky: HEWEY: 15 years old. 

Hoodans: WAYNE: 15 years old. 

TicciSans: TONDRA: 16 years old. 

Saint: LEONIE: 14 years old. 

Birth order: Bean, Cole, Tondra, Hewey, Wayne, Leonie, Silky, BoBo, Addy

Okay so I also drew a pic with all of them so here you lads go. It's a bit rushed since I'm tired and not fully shaded so just ignore that. Wayne's left eye light is the proxy symbol, it's a bit hard to see.
