10. "It gets easier."
When my kids were 1 and 3 and both screaming their heads off at the park one day, a mother chasing her kids on scooters sashayed by and called out, "Don't worry! You're at the hardest part right now!" My heart swelled with love for her. Lady, whoever you are: a thousand thanks! We all know, of course, that being a mom never actually gets easy. But it really helps to know that those eternal difficult afternoons your kids put you through (at every age) are normal, are not your fault, are worth every second. Which is why every mother should get a guardian angel who whispers in her ear (at every stage): "It gets easier. Soon."
