It states that flying cross-country with an active 19 month old baby can be challenging. Here are some tips to help make it a smoother experience:
Bring plenty of snacks and drinks, and pack extra in case of delays.
Take plenty of toys and books for entertainment. Consider stocking up on new items for the flight.
Bring a small blanket or pillow for comfort.
If you are able to, book a window seat with an empty seat next to it – giving your baby space to move around.
Bring a change of clothes in case of spills.
If possible, plan your flight during a nap time or bedtime and bring a sleep aid.
Make sure you bring any medications and/or medical equipment your baby may need.
If you are traveling alone, enlist the help of a flight attendant or other passengers to watch your baby if you need a break.
Take advantage of pre-boarding and boarding early to give you and your baby time to settle in.
