Idea from flibbit5993 on the PJO amino (where I used to write my headcanons RIP)
-Percy's sister has to baby sit when the 7 and Nico/Will's go out together and hang out
-Nico and Will are the ones who arrive early
-Nico would act like he totally trust her and then will hands her a 3 page guide
-Nico starts going through it while Will looks totally bored
-Nico and will adopted twins that are clear sighted mortals
-Leo and Calypso drop off late and don't stay longer than 2 minutes
-Hazel and Frank are always helping out in the legion so they aren't always around
-so their kids learn to get along by themselves
-Hazel and Frank's child help Percy's sister baby sit by keeping the kids calm and playing with them
-When a kid cries Frazel's kid is the first one there and always calms them down asap
-Jason has two kids. One 13, one 5
-The 13 y/o thinks he doesn't need a baby sitter
-he really does though because he burns himself on the stove all the time
-and the 5 y/o is more like Jason in the sense that they are wise beyond their years and follows the directions perfectly and also has pizza on speed dial
-Percy and Annabeth have a smol child
-They love playing with trains and stuff
-mess with their trains and they'll start crying
-Jason and Piper's kids are the oldest
-Will's and Nico's are the youngest
