How can i keep my baby from getting jet-lag?

Sunlight : Jet lag is caused by switching time zones suddenly in east or west direction; this causes your internal clock to be out of synch with the 'real world'. Jet lag often creates sleep difficulties, irritability, upset stomach and headache. Your body uses sunlight and melatonin to set its internal clock. Take it easy the first few days and expose your baby to daylight to help reset his internal clock.

Outdoor light: A few days before you travel try shifting baby's bedtime 20 minutes in whatever direction towards the new time. Once you get to your destination allow baby to eat on demand and with older children adjust mealtimes to match your new time zone. During the day spend lots of time outdoors in the natural light. It may take a few days but you will all adjust.

Proper wake up time: After changing time zones, be sure to wake up each morning at the proper time of the new location. This will help one's body adjust to the new location. Also, keep the window shades open and the lights on after waking up. Sunlight helps tell the brain that it is truly daytime. When it is time to go to sleep, make everything dark again.

Same as you.: First things first, count the number of time zones that you'll jump. Then, add that number to your baby's normal sleep time if you're going east, and subtract that number from your baby's normal sleep time if you're going west. Try to adjust your baby's sleep, one hour at a time, in the right direction the week before your trip. And most important, remain patient.
