I'm the last one, so could be the last to give birth. We are all finding out the sex very soon so it might make all this easier then once we know. However with dc1, I really loved being set on a name before birth, we had a back up favourite for the opposite sex just in case the scans were wrong! 
However I'm really worried that I'll be the last to give birth and one of them will choose the name I have picked. We haven't discussed names but I know from previous conversations years ago we may have similar tastes.
Would it be batshit in this instance to still use the name we'd picked?
I'm worried I'll loose the plot if I have to let go of the name hours before giving birth and pick another when it's taken us about 2 years to agree on a boy/girl name, so it's not like we have a few we like!!!
We all have different surnames if that makes a difference?
