What's the safest way to get around Europe with a 9-month-old?
I appreciate your dilemma. From a safety standpoint, the best solution is to rent a car and use an infant
car seat. Many car rental companies do rent car seats, so you might not have to take your own. However, be sure to make certain of that before you leave home. You should also take into consideration that driving an unfamiliar car on unfamiliar roads may increase the risks of driving. You are correct that in most other countries, just as in the United States, buses and trains do not have seat belts or infant
/child restraints. Good luck, and enjoy your trip!
