Baby voice

My son is 3.5 and at times he uses a “baby voice”. I think it’s developmentally normal. My husband thinks he sounds girly when our son uses this voice. So now every time our son talks my husband is always correcting him and telling him to talk “low and slow”. It’s literally driving me crazy and quite honestly, giving me anxiety. I almost don’t want my son to speak around my husband. I’ve spoken to my husband about not correcting him all the time but he doesn’t agree with me. Any suggestions? I’m about to lose it.
