I need some advice. DS is 17 months and is *this* close to figuring out how to open the child safety cabinet locks. He's already figured out how to open the front door child safety lock (on the third try). Any one else have this issue and how did you keep the chemicals under the sink from a curious, crafty toddler? I watch him a lot and I've started talking to him about how things under the sink are dangerous and one of the few no-no's in the house. He loves going to the forbidden cabinet and signing to me that it's a no-no area and dangerous *facepalm*. Ideas?
