Here's one that falls into the category of "Things Nobody Tells You Before Kids" -- Being a parent requires tremendous stamina. Seriously, if someone had informed us of how much chasing was involved, we might have at least done some extra cardio-training pre-pregnancy. And moms on Twitter this week were quick to point out how much running around they do, either after speedy children, in order to get kids to move faster or just to win a race (for once).
Other funny parents revealed more about the challenges involved in raising kids, including many that are most amusing to those who have been there. (Oh, hello tantrums over shoes and banana peels.)
