This is a hard question to answer because there are so many places you could visit. That being said, pediatricians have a number of concerns about travelling abroad with young infants.
It’s important to make sure your baby has had all of his standard immunizations before travelling. However, some foreign destinations require special vaccines, many of which cannot be given to infants. Similarly, some countries require preventive medication during travel, e.g., malaria prevention, or insect repellent to reduce the risk of mosquito-borne illness. Most preventive anti-malaria medications are not approved for infants. Further, the American Academy of Pediatrics (AAP) does not recommend using DEET-containing insect repellents in the first two months.
Although most babies are healthy, you need to consider the medical facilities that would be available if your baby became ill while you were away. Pediatricians are particularly concerned if a baby develops a fever in the first two to three months of life. Dealing with a sick infant is difficult enough when you’re at home. Having to contend with an illness while you are away is even harder.
Babies are creatures of habit and travelling can easily disturb their feeding and sleep schedules. This is particularly true if you have to take multiple planes to reach your destination or if you are moving from one time zone to another.
