Bottle #1 = One large bottle of alcohol.
Bottle #2 = One large bottle of Phenergan.

Try part of Bottle #2 on Child.
If he doesn't sleep, add remnants of Bottle #2 to Bottle #1 and consume yourself.
Then you won't care about what happens next!

Seriously...

Make sure you have a fabulous First Aid kit. Make sure you've had your vaccinations. And stay somewhere you know will have an English speaking doctor on hand.

And don't forget your travel insurance!

Have an awesome time!
