Cousins with the same name?

My sister just had a baby. She and I grew up EXTREMELY close. We’ve always been best friends. She’s 28 and I’m 23 now. The last two years, our relationship has been very strained and we’ve hardly seen each other. She didn’t even tell me she was pregnant until she was about 6 months along. Well I am also pregnant. She just had her baby and sent my parents and I a group text introducing the baby. It’s the same first name my husband has already picked out for our little girl due in a month.

I hope our relationship isn’t strained forever. And they’d be cousins with the same name, but husband and I have already decided on this name. She didn’t know we had chosen it.

My question is should we change it or keep it the same?
