So, I'm gonna time skip, so I'll put if babies are born in a one-ish year time skip. Also, I'm very lazy, so Percabeth is married, and Franzel is married. I may go back and do it later, but for now, I want to get as much of the main plot done before I go back and do other things. Also, ignore the years, it was just so that I could remember which baby came before/after which one. So. Here's the tea:

Jason and Piper:

Gender: Girl

Name: Ava Isa Grace 

Meaning: Ava means Eagle. And, you know... sacred animal? Never mind

Birthday: 7th September 2020

Godsparents: Percy and Annabeth

Leo and Calypso:

Gender: Girl

Name: Robyn Phoenix Alice Valdez

Meaning: Robyn means fire, Phoenix because Leo rose from the ashes, and Alice because it means magic, from Calypso

Birthday: 11th September 2020

Godsparents: Jason and Percy

Percy and Annabeth:

They have just had their second child at the time the story picks up

Gender: Boy

Name: Nathan Hugo Kai Jackson

Meaning: Ethan and Nathan kind of sound similar, if you think hard enough. Hugo means 'mind or intellect.' And Kai is an intersex name that means sea 

Birthday: 2nd June 2021

Godsparents: Grover and Estelle

Piper and Jason are expecting, and they are almost at their due date. 

Hazel is also pregnant, and almost ready to give birth

Grover and Juniper are also going to have babies, but not for a while yet. Juniper is 4 months pregnant. 

Also, for those of you who remember Kiki (the daughter of Demeter who lost her baby, and then Will and Nico got really scared and upset about it), she started dating Clovis because she had trouble getting to sleep because of the trauma. So yeah. Now she is expecting a baby, but only Clovis and Will know. She is two months pregnant, so it's sorta irrelevant at this point. But yes. It is important, so don't think I'm going off on a tangent. 

There you go, just so it isn't confusing when the story picks up again.
