Name regret: what should I do

Ugh my baby is almost 5 months and I’m really struggling with her name. I never found one that I LOVED but my husband loved Johanna. So she goes by Jojo which I love love. But I really think I want to change it to Josephine. Middle name is Jane. It’s so hard to know what to do. My husband will let us do it but does prefer Johanna. Helppppp

Edit: Jane is a family name so likely keeping that

Edit 2: honestly so glad I posted. Y’all have helped me so much!
