You're on a crowded airplane or train and your baby starts crying and won't stop. What to do? Try to keep smiling. Remember your own anxiety will just give the infant more distress. Make an effort to calm the baby, but don't obsess about it. Some parents bring along foam earplugs to hand out to fellow passengers, just in case. The gesture can head off dirty looks you might get otherwise.
Expect everything to take longer and leave plenty of time. Hurrying can be as hard on your baby as it is on you. Also, remember that most people like babies, and flight attendants and others are often willing to help you out.
When you finally reach your destination, congratulate yourself. You've met the challenge and can relax -- until it's time to return home.
