DD1 was Chloe til about 20/25 weeks. I'm glad I changed my mind, because she has way too many Chloe's as friends

DD2 was Shallae from 13 weeks. We told people the name we were thinking of & I loved it.
But at 37 weeks it just didn't sound the same. I don't know what happened, just got over it I think. We picked a name we agreed on at 38 weeks & I settled on it. I've always wished I had time to find something else, but her name more than suits her.

DD3 was also up in the air til she was a few hours old. She ended up being a name that was never even on our list! She was going to be Kayla, but we were never settled on that name.

DS's name was on our list from before DD1 was thought of. I had other suggestions, but it never changed.

I never bought things with the names on them before birth. I never told people we had a definate name, because they were never 100% to me until they were born & named.
BUT there's nothing wrong with changing your mind!
