Amended return question

My boyfriend and I live together and had a child in 2024. He makes more money than I do, so I had planned on him filing head of house and claiming our daughter as a dependent. I filed my taxes before his, and put her on my taxes as a non-dependent.. that was a mistake, as when I went to push his taxes through, they were not accepted for using her social more than once. I amended my taxes and removed her from my household entirely. My question is, do I need to wait until my amended taxes are accepted to file his taxes? Or can I do it before and his taxes will still be the same? I don’t want to mess his side up. Is this going to make his taxes take as long as my amended taxes? 
Thanks in advance for any help on the subject!
