Belly Binding.URGENT

Okay so here is the deal, I gave birth 6 months ago. After giving birth I did use a "faja" which is what we call it in Spanish which is a Girdle. However I got lazy and stopped using it. I was also sooo tired as a new mommy and really didnt have time to focus on me! Now that my little person is alil bigger and has a schedule I want to start wearing it again! Is it too late ??? I feel really down and depressed because my husband body shames me. I know he is an ass. But I dont want to let it get to me and I want to this for me not to please anybody else. I want to feel and look good for the summer. Happy mommy = happy baby! Pleaseeeee help me! I am also going to start going to the gym again. Since my V was hurting sooo badly after birth I couldnt really work out.
