Postpartum belly help

Hi everyone. I’m embarrassed so I’m posting anon. Lol.

I have had two children. I’ve struggled on and off after my first child with losing weight but I was to a point where I was happy with my weight and my belly wasn’t so saggy and gross looking. Then I got pregnant again.. now this time around, I lost like 50lbs but still need to lose at least 15lbs more. My belly is now so saggy and I’m struggling to lose weight, stay on track, struggling to keep positive. I love food and I’m a big time snacker. What can I do to lose this belly with exercises and what kind of food/meals can I eat?
