If there is one thing I've learned since having kids is to never say "I'd never". All it takes is one off-handed comment--along the lines of "I'd never feed my children McDonald's!"--for you to find yourself on a lonely stretch of road with a screaming, starving child and nothing but the Golden Arches or Doublemint gum as dinner options. Suddenly, McNuggets start to look pretty damn healthy and you look like an ass.
Anytime I start to criticize a mother (shameful, but it happens!) I stop myself because I know what's coming.
I call it Mama Karma and I've learned to respect it.
Let's say I'm at the park and some kid starts to cry because they don't want to share the sandbox. I mean, come on! You're at the park, right? Before my eyes are done with the involuntary eye rolling, guess who's kid starts screaming because a baby touched him and THE WIND! IT IS BLOWING! WAAA!
I think most of us have experienced this, and this is why the people who tend to hold doors open for me when I'm pushing a stroller and trying to balance a huge bag and a coffee are other mothers (or fathers!) pushing strollers. Because they know. We have to watch out for each other.
