I was thinking some more about this - what about chewable medications like baby Aspirin and the like? Also - I am thinking of bringing some matchbox cars and something similarly small for the girlies...I can't wait to see what your final weight is (assuming you've got 50lbs to work with) and what all you end up with! I won't have a ton of room since we're there for a short time and will only have carryons, but I suspect we'll pack them well with some goodies for the kiddos.
