My boys are 2.5 years old and they STILL pee on the floors
they only get roam of the house when I am home. They do sleep through the night with no accidents though and have since they were 4 months old. Ive had a 'phew that was pure luck' moments with things they have chewed while I was not in the room (like my laptop cord that was plugged in) and the chewing lasted about 4 months. About 4 months to 8 months they chewed nonstop! My best advice on that one is during this stage, put them in an indoor pen, this will save your walls and baseboards and the bottoms of your cabinets. Mine chewed all those things up, holes in my walls... uuggghhh wish I thought of the indoor PEN, not just gating them into a room to minimize damage. Good luck!
