Once you have the experience of trying to get a baby wipe out at 3am while a baby is crying, you'll realize they already come pretty close to vacuum sealed. :)

Not just crying but legs kicking and hands trying to grab their own poo while you try and open a bag of wipes. I think you need 5 arms to handle that situation.

Haha. It's recently gotten worse at nearly 3yo, because he's much stronger and thinks playing with poo is funny. I've mastered the art of several wrestling holds, could probably go pro.

Haha. I think a blog article on this would be helpful to me. :) Still learning on holds/wipes/cleaning and how to maximize my two hands.

Unfortunately I don't think this knowledge is transferable! I recently changed a friend's toddler, and nothing worked. She was a kicker, where my son tends to twist his legs around to gain leverage and flip over. I think it's all stuff you figure out by trial, error, error, and more error.

Reminds me of that famous anecdote where NASA invested a million in developing a pen that could write in zero G, while the Russians used a pencil.

A fictional anecdote, FWIW:

Apparently, graphite shavings in air filters are bad news. One has to wonder if nice mechanical pencils would be too bad, though.
