Hi Lisa! Single dad here (one daughter, age 7). I feel you on this! I think u can use Hinge, Bumble or other popular dating apps, the main thing I did was just put it in my profile from day one. "Proud dad to an amazing 7-year-old" right in my bio. Yeah, some people swipe left because of it, but those aren't my people anyway. I'd rather filter them out immediately than waste time chatting with someone who doesn't want to date a parent.
