Here's where I'm coming from, just to get my bona-fides out of the way. Two sets of twin girls, born eleven months and one week apart in July 2004, and then June 2005.

1. Just yank the knobs off and push them on when you need them 10X easier. And we eventually gave up on that, because if the knobs are the usual push-in and twist type, even relatively precocious and bright kids will have a hard time turning them even when they're learning to use the stove when they're older.

2. By the time they were old enough to really strew the pots and pans and tupperware about, they were old enough to defeat the drawer catches/locks, and the 2-3" of opening the locks do allow, their little hands can get in there easier and get all kinds of shit anyway. Put a real locking lock on the chemicals and call it a day, the kind that looks like a Western cowboy bolo-tie made of two heavy duty zip-ties, with heavy spring buttons works well.  The problem with the drawer locks is that the angled plastic hook that locks the drawer and catches on the cabinet frame, it just rounds off, and a good yank and the drawer or door pops open anyway.

3. Mine were never too aggressive about the outlets, but any plugs that don't pull out easily with just fingers will work fine. The way my house was set up, most of them were covered by furniture anyway.

4. What are you missing? Baby gates. Not even so much for "safety" like in stairs, but just to keep them confined to one or two rooms set up for a toddler's play when they're first walking so you can go to the bathroom, or tend to a pot on the stove and have five minutes of peace in which to do it.

Just gating off the whole kitchen if it's not a large archway or open concept might be easier.

The metal foot pedal kind of gate is the best, the wooden and plastic grid ones that sort of ratchet and/or the adults just step over them, you'll get tired of those fast.  This kind also has the pressure screws & pads to hold it to the wall, much better than nailing/screwing for stuff you'll be taking down within 3 years.

Baby Gate, foot lever lock.

Also, a bouncy seat and the Baby Einstein DVD's/BluRay's after about 6 months when they're able to focus on the TV will save EVERYONE lots of stress.

Baby Einstein DVD's

Especially the Baby Mozart and Bach to start with.  They make a face like Dave Bowman does in the last 5 minutes of 2001: A Space Odyssey.

Yes, this.

Add a chain-slider up high on any egress doors so they don't wander away outside. Once they're old enough to drag a chair over and defeat the chain, around 4-5 years old, they're probably old enough to not wander outside and die in a snowbank or something.

they have new firmware to fix that
