Gastric Sleeve Surgery After Pregnancy

I am looking into getting gastric surgery after I have my baby and I just wanted to know if any of you ladies did so. If so how long did you wait postpartum? I know that having a baby is hard on your body and it needs time to heal afterwards but I want to get a generalization of how long I can expect to wait to start my weight loss journey. I went through hoops and hurdles before I got pregnant to get it and found out I was pregnant four days before I got the phone call to schedule my surgery. All information would be helpful!
