Ok so my girls sleep in the same room and when I have my 5 year old nephew on the weekends he sleeps on a mattress on their floor. I love baby gates, I use the ones that's like a door but the kids cant get it open ( most adults cant). My kids don't have a problem with them because they are use to them but my nephew had a serious problem with them when he started staying every weekend. He's gotten use to it( he better because it not going anywhere). But I woke up this morning to him going up the stairs cuz he'd climbed over it, which is so dangerous. My question is what does everyone think about baby gates and at what age should you take them down?
