Congratulations for a start! I have B/G twins too, have yet to meet another set (adults aside) in RL. As your DH loves Clementine and you love it too, then lock in that one and go from there. I think given Clementine is his ultimate favourite you should nominate your favourite boys name and if DH likes it then job done. So Jasper & Clementine then - lovely! Good luck.
