I didn't sign up for this

You remember when you had all these dreams of how lovely motherhood would be?
You'd look at your baby and he/she'd look at you and then he/she would coo at you and you'd smile. (Happy music playing) Then the diapers would be minimal and you'd both sleep good hours and you'd feel rested enough to shower, wash your hair, AND shave your legs? You'd never smell like vomit or poop, that you'd always get a shower, and would never have to figure out how to fit into your pre-pregnancy jeans?
Then the reality kicked in and it could be as ugly as the Uma Thurman movie Motherhood's attendance numbers.
Lack of sleep, missed bathing days, leg hair long enough to braid, and all your clothes have vomit stains on them are the gold standard, but don't look at these things as something horrible. I don't' want to sound all Julie Andrews and Raindrops on Roses on you, but no mother, I don't care what they say, hasn't gone through all of this in some form or fashion.
Having such a false sense of what to expect, is well, expected. Motherhood is as beautiful as it is ugly, fun as it is miserable, and memorable as it is those moments you'd want to forget. No matter how old or well behaved your children are, there are parts of motherhood that aren't enjoyable.
Even though my children aren't babies anymore, there are days I find myself saying "I didn't sign up for this part." I didn't sign up for the headbutting, the having to explain every single thing, or the middle of the night stomach flu, but I do know that children very much want to learn, they want to be heard, and they don't want to be sick. I can't be mad at them for wanting to understand what I'm trying to get them to do, but I can get very frustrated when they still don't do what I've asked them to do.
Parenting is the ultimate on the job training and it lasts a lifetime so you're allowed good and bad, wonderful and horrible, memorable and forgettable days during the journey. Don't beat yourself up if your children aren't perfect. Honestly, who wants perfect children? I don't. I want kids to keep wanting to learn, but I know with that, I'll get days, moments, that I just didn't sign up for as a mother.
I'll keep going though, keep trying, and that's what makes a Supermommy.
