I've decided to end this congrats now, as I don't feel I have time to keep it up.
You should all have 4 letters left. You may choose the genders and names for the last two children as well as if they are single births or twins. The only requirement is that you use the four remaining letters as their initials. For example, if you have EJPX you could have a DD with initials EX and a DS with initials PJ.
