Here's a post from our partners at BabyCenter! Every week, we bring you the best parenting and lifestyle stories from the experts at BabyCenter, including this post about parenthood.

I've been a mother for almost four years and I wish I could say that I've got parenthood down pat. Every day offers new challenges that often leave me feeling stumped. If I can accomplish at least half of the things on my agenda, I'm happy. Those who aren't parents haven't got a clue what my husband and I go through. But, those who are can empathize with our situation. Here are 10 things only parents can understand.

  1. Being sick all the time. If you're a parent to small children in daycare, then you know what I'm talking about. Kids can be susceptible to all kinds of germs. I've experienced this with both of my children. They would catch a virus, which leaves one of us having to call out from work. Then it becomes a game of tag with each of us taking turns getting sick.
  2. No sleep. It took Princess a while to start sleeping through the night. Once we got a routine down, I got pregnant with baby number two. Right now I'm averaging around five hours a night.
  3. No privacy. Nowadays I can't enjoy a 15-minute shower without one of my kids needing me for something. Either my daughter would barge in to ask a random question or her baby brother would need my attention. Sometimes I've had to bring him into the bathroom with me.
  4. Can't sit down to enjoy a meal. Having an infant keeps you on your toes. My husband and I have a rule that we don't eat unless the kids eat first. There's usually so much going on that we end up taking turns at the dinner table.
  5. Can't get through a movie. Making it through any program is challenging. With two kids around, we can never hear dialogue. It's way too loud! By the time we get ready to put the kids to bed, my husband usually falls asleep in minutes.
  6. Always tired. Hearing people who aren't parents complain about being tired makes me want to scream. There is rarely any down time. Being home is more work than actually being at work. My hats off to stay-at-home-moms. I don't know how you do it.
  7. Traveling can be tedious. Before becoming a parent, getting in and out of the car was a breeze. Now it takes about 10 minutes, sometimes more, depending on the time of year and the amount of things we have to tote around. I used to be one of those people who'd refuse to wait for the parents with small children to load everything in the car. Now we've become those people.
  8. Assembling baby products and gadgets. Putting together baby items isn't always simple. It can take hours to get it right.
  9. Having a messy house. Our house has become cluttered chaos since kids came into the picture.
  10. Being a worrywart. There's not a day when I don't think about my children's safety.

I wouldn't trade being a parent for anything in the world. The love I have for my babies run deep. There's nothing I wouldn't do for them.
