Birth Control

I am due September 2nd and have already given thought to BC after I have the baby. Hubby and I talked about him getting a vasectomy but he isn't ready to commit to permanent BC, idk if I am 100% either. Anyways, I haven't been on any BC for the past 6 years or so. I know I want non-hormonal BC and I'm seriously considering getting the copper IUD. Anyone used it before? Opinions? Any other non hormonal BC methods you'd recommend?
