Hi Jilly!
We have logged 6 international trips with our 33 mo old and have learned a lot! Being prepared and organized is the key…but the most important thing to pack is a sense of humor!
Packing: Space bags rock! (the kind you roll the air out -got them at Bed Bath). Check the overseas luggage requirements -they are super strict (JC Penny sells amazing light luggage). You can pack important essentials in the carry on (lovey, blankie, few paci’s, etc). Pack your first night’s needs in front pocket of luggage so you don’t have to rummage through everything you will probably be exhausted.
Airport: changing planes? You may not get your stroller at the connection airport especially if connecting int’l. A large backpack is a lifesaver as a carry on! I had to lug my sleepy 22 mo old and my carry on through Heathrow T5 for a 4 mile walk...after the flight attendant SWORE we'd get the stroller at the gate...neither one of us was happy about it. If traveling with your hubby let him pre-board with the bags and get settled (make sure he doesn’t have your boarding pass – we did that once!) and run that 2yr old around as long as possible before final boarding – you will be thankful later!
Carry on: #1 item is large pack of wipes! A frozen washcloth in a Ziploc comes in great for sticky faces. Most airports allow you to take extra liquids in addition to your quart size ziploc bag for child’s food/drink as long as you make the screener aware (pack in its own Ziploc and be sure pull out for screening). I suggest to pack lots of non perishable food/snacks for the flight & don’t rely on the airline for anything chances are they can’t even heat food for you (Put quick meal in luggage too- we arrived in Italy on a Sunday with everything closed and were thankful for the tuna lunch kit!). Small juice boxes are great (save the sippy cup for water). Pack enough diapers (nighttime ones) to have one per hour of traveling. I read once and I was SO thankful because on one flight my child got a stomach bug and pooped through 10 diapers in one flight. Pull ups are way easier to change on board. Don’t forget a wipable bib. i recommend to pack two changes of clothes for your child (including shoes) and one for you (space bag!). For yourself, wearing dark breathable clothing hides messes and dries quickly…you will get messed it’s just a question of when! My hubby and I take bets on the when and what. Last trip he bet on pee in the first half of flight and won himself a foot rub...so unfair :-)
Flight: I know I'm a more relaxed traveler when im mentally prepared. Deliciousbaby.com has awesome travel tips. Try to write down 10 toy free play ideas and stash in your bag – it’ll make you feel good knowing you have an arsenal of boredom busters (i.e. a cup of ice and a coffee stirrer can be a great game of making soup for Mommy). At this age, plan around a 15-30 min attention span. We did the toy to unpack every 30 mins and it was just perfect (short kids shows on the ipod were invaluable too - movies were too long). Think double duty for what you bring (toys that can be a bath toy, wrap toys in coloring book or magazine pages and then play look and find with pages, etc). Be sure to stash away a few things for the return trip as for us the day flight home was the toughest leg. The best inventions ever are Aquadoodles and Crayola wonder products. If you are flying overnight –stick to your reg. routine at home (pj’s, book, lovey, blankie etc) to help your child sleep. I swear by the apple sauce in squeeze packs – during takeoff/landing I give one to my child and by sucking out the applesauce it helps her ears better than any paci/sippy cup. The descent is harder on their ears than take off.
Products: What can't you live with out? For us, Europe has the worst stain fighting products so i bring some tide stain packs. Wipes were also $14 a pack so that was worth packing an extra. Diapers are avail everywhere but might be hard to find your size/type bring a good stash to give you time to find them (know your child’s weight in KG as the size numbers are different – plus you may need it for medicine in an emergency). No need to pack the soap/shampoo - half of the fun of traveling is seeing what kid products they use so enjoy the experience! Personally, I can't leave home with out: Tylenol/motrin rapid melts, disposable sippy cups, and Gerber yogurt drops (hey i like them too).
Hotel room: a good roll of painters tape will secure anything from covering plugs to securing light cords (or the occasional 2 yr old!). International plugs are different and carry hefty voltage but at least they’re usually waist high. Ask the hotel in advance the size of the crib – some have cribs and some have pack n plays so you can bring the right sheet. Having breakfast handy the night before helped us. Local grocery stores usually sell small packs of shelf stable milk/cereal, etc so you have easy inexpensive breakfast in the morning because jet lagged parents move much slower than regular parents!
Sorry such a long post - have a safe and enjoyable trip! Traveling is one of the best adventures you can share with your child!
