i had the same problem at first he would not even put any names out there but he finally starting going through some names in November and we finally picked one, im due in March so you can believe the wait.
You both will eventually find the perfect name for your Daughter! :)
My Husband and I had the same issue while choosing a name for our baby boy! We went through multiple lists of names trying to find the perfect name! (We chose names years ago while TTC, and the names on our list just didn't sound as great anymore).
We fell in love with the name Declan, and I looked and looked for a middle name and he and I fell in love with the name Blake. Declan Blake!
When he and I were choosing our oldest Son's name, we fell in love with the name Brantley. Brantley's middle name is Glen after my Husband's Dad.
