Now that JD is crawling and climbing (EVERYWHERE), we knew it was time to get a gate so he doesn't accidently tumble down the stairs. My wife's sister had purchased a cheap wooden one to save on costs, but after looking at ours, they had serious gate-envy and post-purchase regret. We picked this one up at Babies 'R Us, for about $70 - The First Years Hands-Free Gate. Not the cheapest thing in the world, but it's worth the extra bucks.

We got this based on a recommendation from our friend - who love the hands-free capability (step on a pedal and push with your knew or hip to open), and has an extra extension in case your hallway is extra-wide. But the best thing about it is, there are NO screws - so your walls are hole-free, and the gate is still securely fastened.
