B., please forgive my lack of people skills in this response. My intention is absolutely meant to be helpful, not insulting...that said, here is my advice: I have 3 children (girl, age 9; boy age 7: and girl almost 3) and I have NEVER had to install a baby gate or waste money on different products to figure out which worked. Instead of child-proofing your house, try house-proofing your children. If you can train a dog to sit, shake, and roll over, then you can certainly teach a child what they are and are not allowed to do. First, carve out a specific time (which is definitely the hardest part of this task for me) and use this time to set up the scenario that you are trying to avoid. When your child(ren) attempt to open the gate, if you choose to keep the gate, then get down to their level and use your "mom voice" (not a happy sing-song voice) and tell the child "YOU ARE NOT ALLOWED WITHOUT MOMMY! DO NOT OPEN THE GATE!" Do this repeatedly every day for just a few minutes at a time. USE TREATS to encourage. If you are a mom that doesn't use candy (I use M&M's sometimes--one at a time and a bag lasts FOREVER!), you can also use the childs favorite crackers or raisins or strawberries. Reward, reward, reward, with showers of praise when your child walks past the gate without trying to break in. You will only have to put a few days into this before it becomes a habit for your child to seek your approval when avoiding what you want them to avoid. I assure you, this process is very successful in teaching any child over the age of 1 for almost any scenario. If you use corporal punishment (aka spanking) in your home, you can also use a small dowdle-rod to deter unwanted behavior. A small "pop" on the hand or back of the leg to give them a sensory reaction. **I do not mean hard enough to hurt, just enough to associate their negative behavior with a negative response...and a positive response (praise or treat) for the positive behavior. Once the lesson is taught and learned, your job as a mom will be so much less stressful overall.
