Little pouch

Chantel

So I’m breastfeeding and My body is small but I still have a pouch and notice my bum is flat. Any moms know of good ways to get rid of this ? I also don’t know why my bum went so flat and saggyish. Any moms know of good workouts or certain things they did to help? Btw the pouch is small but covered from my high wasted tights.
