Naming Baby

My husband keeps shooting down EVERYTHING i suggest for our baby boy's name... but has nothing of his own to contribute. Everytime I bring it up he finds a way to shift the conversation to another topic. I am almost 7 months and I know we 'still have time' but I would like this time to entertain a few name ideas, not still be arguing about just communicating about it in the first place. Has anyone else dealt with this? How did you get the ball rolling? I am at a loss 😑
