Waist trainers right after giving birth?

Do you ladies think it's safe to wear a waist trainer almost right after giving birth? I want to bounce back to my prepregnancy body asap being due this month, and my 21st birthday in April. I have some friends that bounced back so quickly or even look better than they did before they were pregnant and I'm so jealous! Lol. I know that breastfeeding also helps out so I'm planning on doing that as well. Anyone have any suggestions? Tyia 😊💖
