Should I tell my partner I don’t like our baby’s name before doing the birth certificate?

We just welcomed our baby girl and couldn’t agree on a name leading up to it. We had a handful and decided we would see in hospital. Well he really wanted to name her before we left and I was so on cloud nine and not thinking clearly and agreed to a middle name I really don’t like. It’s an honour name for his great aunt. I don’t want to disappoint him. Was thinking of coming up with some derivatives. The name so far is Evie Mae Irene. The part that bothers me is Evie was like my third pick name too, so I was already compromising.

We haven’t filled the birth certificate officially yet, but he made the announcement to family and great auntie Irene is over the moon. Ahhh.
