I had to put a hook on the top of my kitchen door to stop mine getting in there if I wasn't in there first. One of the biggest challenges was the toilet. Yes, I wanted them to use it whenever they wanted but I really preferred it if they didn't go in there to play with the toilet block or the toilet brush (yuck!). I had twins and the teamwork they had was incredible. It was really hard to stay one step ahead. :)
What flummoxed me was when one of them at age 2 mastered the art of opening baby gates ... designed to resist children up to the age of 5. What's more, it was my daughter who has Down Syndrome who worked it out ... :) She opened the gate at the bottom of the stairs, climbed up several steps and just sat there and waited for me to notice...
