Hard to picture myself "sexy" again since being a mom?😶

Had my first baby 5 months ago and I've been working really hard to get back to my prepregnancy weight. Well so far, I have lost weight but now when I see myself in the mirrow can't see myself sexy anymore. Like I've been trying to dress alittle sexy for my SO but when it comes to it im just like Nahhh...and take it off. I feel like my mentality is just 'mommy-mode'. How can I bring back the sexy?!😩Or am I just going through a phase?
