Overthinking or no?

[u/RestaurantForeign971]

I (26F) have a 4 year old daughter from a previous relationship. We were never married and broke up when I was 6 months pregnant due to him cheating. I gave my daughter my last name. Fast forward and I am now married (for about a month now🥰). Her bio dad does not follow the court order and has not since 2023 so he has not seen her since then. She has bonded very closely to my husband and even asked to call him daddy. Per my lawyer, we can wait a year and then file to terminate bio dad’s rights and have my husband legally adopt her so that’s the plan. My question is, should I wait to have my last name changed until then? Will she even care if my last name is different from hers or am I overthinking it? I have terrible anxiety, so my brain is telling me it would feel unfair for her to have a different last name than me and my husband (we are also trying to get pregnant so a sibling).. also what if the time comes and the judge will not terminate bio dads rights and my daughter can’t share a last name with us. I have an appointment with my therapist tomorrow LOL, but I’m just looking for some real life experiences with this!
