In DOI,JR says that as his oldest child,Beth had a special place in his heart.
I have all the 'first-time having a baby' memories from my first child,but I love both of mine equally.
I have also wondered if JB was indeed JR's..but I guess with the dna testing ,they would know,since they ruled him out as the dna source(?)
Since JR was older than PR and already had 3 kids,maybe he just went along with having more b/c PR wanted kids of her own.and by the time he got to the 5th one,he was worn out/worn down as a parent(?) PR did say he had the big v done in DOI.
