Concerns about stepfather

Hi r/parenting, I've read the rules and I believe that this complies with them and is the most appropriate place for this post but please remove and redirect if needed.Christmas day has been a bit dramatic in our house today. I was using my stepfathers tablet to play 'spots and dots' to prevent a meltdown with my three month old daughter this afternoon as it was the nearest device. The search history was wiped on the youtube app apart from one search for 'kids in bikinis' - obviously I'm disgusted and in shock but completely at a loss for what to do.My stepfather works away from home as a trucker and has been known to lend his tablet and laptop to other truckers when they are parked up so that they can watch a movie etc. He has also a habit for wiping his search history so it stands to me that he would have the sense to wipe this 'if' he was the one searching for such material.Obviously I don't want to think that this is him that has searched for such a thing but I'm at a loss for what to do here, I want to keep my daughter safe at all costs. I'd appreciate some advice from other parents on this as I think I'm a little too close to the situation to view it objectively. 7Thanks in advance, One stressed out mama. via /r/Parenting http://ift.tt/2Bzzghy
