You'll need to think about how to get the baby home, typically by plane. Some issues to keep in mind include:
- Seating: Until the baby is 2 years old, the baby can generally sit in your lap. You can generally have 1 baby per lap. If you have triplets, with two adults, you probably need to buy a third seat. Do confirm with your airline.
- Baby Food: You'll need to feed the baby. If you're not breast feeding, you'll have to plan how to handle forumla. You'll need sterilized bottles, formula and water. You can pre-sterilize bottles and travel with them in platic bags. You can pre-measure formula into either plastic bags or carrying containers. Water is more complicated - check with your airline or airport. Your choices come down to trying to carry water inside the bottles through security (say it's baby formula water - maybe you'll get through), purchase water after you've cleared security, or get water on the airplaine from the stewardesses.
- Changing the baby: The onboard bathrooms have limited space for changing a baby, but you'll have to make do. In addition to diapers, remember to carry extra baby wipes.
- Change of clothes for the baby: Bring the appropriate number for the flight.
- Change of clothes for you: In case the baby throws up, goes to the bathroom, or does something else on you.
Some other tips:
- Ear Pressure: If the baby is breast feeding or formula feeding, you may consider feeding them during take-off and landing. This can help alleviate any ear discomfort.
- Sick baby: Check with your doctor if the baby has a cold, cough, or ear infection.
Each airport seems to handle security differently - double check everything with your airline/airport before leaving.
