Best and Worst Comic Pregnancies?

[Nitz the Bloody]

Since I recently went down this road in my own comic, I'm trying to avoid the problems that generally come up with pregnancies in serial fiction, particularly superhero comics. Certainly adding a child to the characters' lives can be material for shark-jumping, so I'm asking if the following conceptions worked or not, and why...

--Franklin Richards? (Sue Storm and Reed Richards, Fantastic Four in the 1960's)

--Valeria Richards? (Same couple and magazine, but in 2001)

--Nathan Christopher Charles Dayspring Askani'Son Summers? (Madelyne Pryor and Scott Summers, X-Men in the mid-80's)

--Mayday Parker? (Mary Jane Watson and Peter Parker, mid-1990s Spider-Man

--Thomas and Billy Williams? (Wanda Maxmimoff and the Vision, Vision and Scarlet Witch maxi-series circa 1985)

--Lian Harper? (Chesire and Roy Harper, the Teen Titans in an era I don't remember)

--Jai and Iris West? (Linda Park and Wally West, mid-2000s Flash)

--Danielle Cage? (Jessica Jones and Luke Cage, New Avengers)

--any others?
