Would be Jimmy/Teddy, day-to-day and James/Theodore, on BC. Please don't say you prefer Jamie/Theo, etc. as we have chosen the NNs we like, but he can pick when he wants to, but while he can't, we have decided on Jimmy/Teddy. Can people also not start with the "I don't get the picking NNs thing, I think that's odd, etc." 
thank you!
Which would you pick???
