We didn't anchor bedroom dressers, but being in earthquake country, any taller furniture in our house (bookcases, china cabinets, etc) is anchored. For the most part, I have always been pretty vigilant about training my kids not to use furniture as a playground. For one, it's a safety issue, and for another, it ruins the furniture. They will encounter furniture wherever they go, not just in our house, and I can't be sure that if I allowed them to climb on furniture at our house, that they wouldn't make the same mistake at someone else's house where the furniture wasn't anchored. It's better to train them to only open one drawer at a time, and never to stand in the drawers. That way, if they're at grandma's house or over at the babysitter's house, I don't have to worry. I really didn't baby proof much of anything in our home, because I'd rather just train them from the start not to do dangerous things, and not to allow myself to feel complacent about safety, ever.
