Excerpt: Not feeling like Mary Poppins today? Whether you work or stay at home, you’re bound to have days alone with your baby that start off bad and quickly get worse….Have a pajama day Hanging out in your jammies isn’t just comfortable, it’s a great opportunity to connect with your inner child, says Yvonne Thomas, Ph.D., an L.A.-based psychologist. Increase your water intake Dehydration can cause headache and exhaustion, leaving you feeling even more tired than you already are. Aim to drink about eight 8-ounce glasses of water per day…Share bad-mama moments “Being able to talk about your not-so-stellar moments as a mom will help you realize you’re not alone, you’re not the worst mother in the world, and your child is not the most incorrigible,” says Yvonne Thomas, Ph.D., a Los Angeles-based psychologist. Venting to a supportive friend or online chat buddies will help you remember there are no perfect parents or babies. And someone will always have a worse screwup story than yours.
