Father Inlaw @ Birth???

[kahmanya]

Hi guys i am 4 months and have to start thinking about my birth plan. My sister in law mentioned to me if i would like to think about having her Dad there, as he recently confessed he would like to see a birth! In his days Dads were not allowed in to the delivery suite. She just said Ros think about it, I can understand if you don 't want to.
I love my in laws to bits they are great people and would love MIL to be at birth, but for FIL to see my Nakey bits is a bit mmmmmmmm. Honestly I don 't know, since he is in his 70's i might consider it, as when in pain i really don't care who takes a look!!!
What opinions can you offer me!! I am leaning towards letting him in as he has been a wonderful grandparent and father.( i am truly blessed with fantastic inlaws!!) is it too icky to have him there???
