We are doing a road trip over christmas too, not quite so far but Adelaide to Northern NSW will be interesting with three small children

DD1 will be 6 and is getting 2 books, power wing scooter (she requested this), 3 small folkmanis hand puppets, pillow pet slippers
DD2 will be 4 and is getting 2 books, a 2 wheel scooter which came with a skateboard, pillow pet slippers, a small wicker case with a tin tea set
DD3 will be 9 months is getting a lamaze ring stacker, small alphabet dino and a toy letterbox

Stockings for older girls will have cheap hairclips, jewellery, bubble bath, nightie, singlet and undies set (wont need to pack as many for our holidays) bubble bath, skipping rope DD3 is getting PJ's, a soft book and a sock moneky (the sock monkey should pretty much fill the stocking!) and a $2 inflatable beach ball to use in Popas pool.

We are lucky as my parents are coming down at the end of the month and bringing an empty suitcase to take some things in for us and once they have opened everything it should be easier to bring home minus packaging

The older girls birthdays are coming up and they are getting portable DVD players (for the road trip ) Cheap as chips had bright lap top stable tables with little lights so they are getting one each to do colouring/mini puzzles on while we drive. Ebay cheap-o pettiskirts as they are into girly stuff. DD2 is getting a night light that doubles as a torch as she likes a night light but her current lamp is really bright even with the lowest watt bulb we could put in it and she is getting a barbie puzzle. DD1 is getting a Princess Jasmine(from Aladdin) doll as she is into princess Jasmine right now, probably because they share a name . She is getting Gellez I think they are called which are in the craft section

DD1s requests were the scooter, an ipad, trampoline, motorised car, new swing set and a mobile phone!!! She has very expensive taste and we had to say no way to most and explained father christmas had to buy stuff to make these things and the stuff to make them costs too much money for every child to get one! Maybe when she is bigger she might get a phone or ipad, like 10 years older!!!
