Pros: stays on, coats well, versatile, easy to store
My mom grew up milking dairy cows. Every day, she used Bag Balm (yes, its really used on the "bag") to keep the cow teats soft and supple for milking. Her friends were all in awe of her soft, strong hands in high school. As a kid, there was nothing this couldn't do. Hands rough from cold winter days? Get 'em wet, rub on some bag balm. Rash? Itchy? Scratched? Mosquito bite? Cracked nipples? You name the skin problem, this stuff helps. As a diaper cream...
-cloth diaper safe if you have a top-loader
-easy to apply
-square container is stable, great for twins b/c the second cutie can't knock it over easily
-easy to use with one hand
-if you apply it over wet urine on skin, it traps the ammonia there and baby will smell funky for a bit. But cleaning before adding a new dipe goes without saying!
I would add, my mom always has a couple open cans, one of which is at least ten years old, and it still looks and works as good as my brand new can. You can get it on thin as tissue paper, especially on wet bums, or frost the bum like a cupcake with ease. The best baby diaper rash cream ever, period.
