Would a daughter of Robert and Cersei be permitted to grow to adulthood, and would it inflame Arryn's suspicions or remove them?
Say any children from the wedding night/early marriage aren't prevented or aborted. Wether because the Fortuneteller she based so much of her life on said to have it, she doesn't hear 'Lyanna' the first time or Olenna Martell turns up and uses her miserable old bag powers to ensure she stays pregnant. Whatever. Either way, Cersei's attempts to dispose of the child fail, people know she's pregnant and she's having the baby.
Would Cersei risk assassination once the baby was born to put it down? As it's not a 'real' (Jaime) child, and a girl, the baby can't be a threat to a real heir in Joffrey. Robert's probably eyeing the girl off to marry to Robb Stark, Tywin probably wants her as a page. Targ loyalists might even try to arrange a quiet accident.
Then we've got Jon Arryn. It took him a bit of research to figure out the incest, but would he even be set on the trail when one child looks like a tiny Robert?

If they had a legitimate child, even only one, Jon may have thought that the other were legitimate as well even if they were blondes, blaming randomness.
