Names are hard...

We are 18 weeks with twins.  Unofficially twin girls (no one else knows that so.. Shhh) we find out for sure on the 3rd.. Ugh soo far away!! It's so hard coming up with names.. Especially 2.. We had boy names that we had actually agreed on.. But now that we need 2 girl names.. I feel stressed.. We don't agree on anything.. And don't want common. We like unique we have an Allivia and Cruz and need cute names.. We so far like Hayden but we don't have a middle name .. Or a 2nd name.. This is probably the hardest part of parenting.. They have to live with this name forever.. Or until they are old enough to change it lol .. Any suggestions??
