Everyone knows that having children is a huge responsibility and it changes your life in ways that you can't imagine.
Now it's easy to understand this statement but to experience the "unimaginable", as any parent will tell you, is what makes the above-statement a universal truth.
There's just no way you'll ever know what it's like to have children until you have them yourself. Babysitting for a day or two doesn't count. Having pets doesn't count, either. But being responsible for a human life, and all of its ups and downs is a trip. And like any life-changing experience, it's going to teach you a few things.
1. Sleep no more.
The art of slumber, as you know it, will be forever changed. Transitioning babies or toddlers from sleeping in the same room as you to having their own bed is a herculean task. Many kids fight sleep like it's the plague too and not because they're trying to spite you - just because they are so in love with you and life that they don't want to miss a thing. It's hard to be mad at them for it, which turns sleep time into a guilt-ridden affair. Your sleep cycle will be changed - forever.
