Are restaurants in Europe kid-friendly?

Most are, but they don't always have high chairs or changing tables. Look for outdoor seating areas; they are generally more forgiving with noisy children than quiet, formal dining rooms.

Should I bring a car seat?

Only if you plan to rent a car. If you are staying within cities and using trains/taxis, they take up too much space and are a hassle to haul around.

Navigating European Cities with Children

Prioritize apartment rentals over hotels to maintain a routine and utilize local parks and public transit for downtime. Limit your schedule to one major activity per day to avoid meltdowns and allow for frequent snack breaks.

Master the transport. Avoid heavy strollers. Use a lightweight, fold-up umbrella stroller or a sturdy toddler carrier. European cobbles are brutal on stroller wheels and navigating old subway stations with no elevators is common.
Use the 'One Big Thing' rule. Plan only one museum, monument, or guided tour per day. Spend the remainder of the time in public squares or neighborhood parks where children can move freely while you observe local life.
Strategic grocery shopping. Visit a local supermarket as soon as you arrive. Keep a 'go-bag' with non-perishables like fruit, crackers, and juice boxes to prevent 'hangry' outbursts when cafes are closed for mid-day siestas.
Handle bathrooms like a pro. Public restrooms are rare and often require coins. Always carry 50-cent and 1-euro coins, and make it a rule to stop at any museum or cafe bathroom before heading out for a long walk.
