When I was pregnant I discussed names I liked with DPs sister. My favourite was also hers, she said she had fertility issues and would be lucky to get pregnant/that it'd take years and may require assistance and asked that I please didn't use the name as she had her heart set on it since childhood. I agreed.
When DD was born we had two other names we liked, though none came close to my favourite. A few hours after DD was born DP kept asking which name I preferred out of the two and I eventually picked to keep him quiet.
Now SIL is pregnant, first month after getting married. The 5 month scan has shown baby is a girl and she's picked a completely different name. My DD is now 11 months and her name still doesn't feel right to me. I appreciate its late to change it, but it'll be her name forever.
AIBU to want to change it?
