My son had just turned 1 when I left his father, and I was concerned about his safety. He was, and still is, too young to reach out to me if he was in a scary situation. We have been doing Soberlink for almost a year now, and it has brought me such peace of mind. I can see what my co-parent's BAC is before handing my son over, freeing me from having to rely on his narrative. I recommend anyone in a custody battle with an alcoholic use Soberlink. I have had 0 issues with it and have been able to protect my son when his dad was drinking.
