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.
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.
