LIGHT packing for a BIG trip

Seriously, how do you travel light with a baby? We will be going to Melbourne for Che Su's graduation this Sunday. THIS SUNDAY. Yikes. I know it is not such a big deal, but I am a bit worried because this will be the very first time Sara on a flight.

I've made a checklist *clap clap* of all the things to bring which can be categorized into this:

1) FEEDING - bib, spoon, hands&mouth wipes, foods (oats with prunes, rusks biscuits and heinz jar), milk bottle, flask, formula milk, milk container
2) CLOTHING - at least 8 pants, 12 tops, sweater, cardigan among other things.
3) DIAPERING - baby wipes, 10 pcs of napkin, 2 pcs of CDs, disposable diapers.
4) TOILETRIES - minyak telon, sebamed, aiken powder, johnsons powder
5) MEDICINE - antiseptic cream, tystatin
6) OTHERS - pacifier, toys, her favourite bunny pillow, blanket, small towel, rubber mat, detergen.

I know some of the things can be bought there but WHAT IF the taste is different, or she doesn't like it or she wants to eat it on the plane? (I am OVERthinking it, I know ;p)

Okay. Here's to hoping that I will not forget anything important. Hee...
