If it works for your arrangement, putting a gate outside the door is a good idea. I do also have one at the top of the stairs. Not all gates are approved for stair use so you do need to check. You'll need to look at where it would need to attach to determine if a gate will work for you too. The height of the banister and other things can make it so that some gates can't be installed. I have the "Kiddy Guard" which we love. It is approved for steps and installation can be adadpted to fit anywhere. It is a soft gate that locks in place after you close it. While not in use, it retracts back into itself so you aren't tripping over it or needing to bother with it when it's not needed. It does require two hands to use, but isn't too complicated - just enough so to keep little hands from opening/closing themselves. I have seen it at Baby USA and I think we ordered it on "OneStepAhead.com"
